Please report your issue to the vendor of the software you are using!
That software should be able to handle whatever you select.
How it operates has little to do with time zone data from this project.
Does the software you are using support updating from tzdata, do you know the
proper process for applying such an update, or has the vendor provided such an
update recently?
The tzdata package contains the following zones for Mexico:
$ grep MX zone.tab
zone.tab:MX +1924-09909 America/Mexico_City Central Mexico
zone.tab:MX +2105-08646 America/Cancun Quintana Roo
zone.tab:MX +2058-08937 America/Merida Campeche, Yucatan
zone.tab:MX +2540-10019 America/Monterrey Durango; Coahuila, Nuevo Leon,
Tamaulipas (most areas)
zone.tab:MX +2550-09730 America/Matamoros Coahuila, Nuevo Leon, Tamaulipas (US
border)
zone.tab:MX +2838-10605 America/Chihuahua Chihuahua (most areas)
zone.tab:MX +3144-10629 America/Ciudad_Juarez Chihuahua (US border -
west)
zone.tab:MX +2934-10425 America/Ojinaga Chihuahua (US border - east)
zone.tab:MX +2313-10625 America/Mazatlan Baja California Sur, Nayarit (most
areas), Sinaloa
zone.tab:MX +2048-10515 America/Bahia_Banderas Bahia de Banderas
zone.tab:MX +2904-11058 America/Hermosillo Sonora
zone.tab:MX +3232-11701 America/Tijuana Baja California
showing the lat/long ranges are +19°24'..32°32' -086°46'..-117°01';
$ grep Macau zone.tab
MO +221150+1133230 Asia/Macau
so it looks like that software is mismatching the country selection somehow.
The tzcode package utility tzselect provides the selection of zones below for
the extreme lat/long coordinates and the country selection, nothing like Macau:
$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", "TZ", "time", or "now".
...
11) coord - I want to use geographical coordinates.
12) TZ - I want to specify the timezone using a proleptic TZ string.
13) time - I know local time already.
14) now - Like "time", but configure only for timestamps from now on.
#? 11
Please enter coordinates in ISO 6709 notation.
For example, +4042-07403 stands for
40 degrees 42 minutes north, 74 degrees 3 minutes west.

listed roughly in increasing order of distance from +1924-08646.

Refreshing the page fixes it, but I was able to recreate it again (navigate with
tab key to “Country” then start to type “Mexico” to land in the Mexico option,
then “birth town” automatically defaults to a drop-down menu of these two Macau
cities.
That software may only be looking at the first letter in Country: try typing
slower to allow it to catch up!
It should also prompt for "closest town to birth town", as many towns are not
included in most software, and it depends on the gazeteer used: comprehensive
global gazeteers are freely available but large:

Good morning, everyone! Allow me to report a bug (see screenshot):
Wanted to try making a new chart now that there’s a patch installed, but now I
can’t choose any Mexican city.

Thanks for that research on Baja California. I installed the attached
proposed patches. The first one is for Baja California and goes back to what
Shanks said about Tijuana, as this agrees with your data. The second one is
commentary about Zapotec timekeeping which I found while looking into the
matter.
