Hi Peter,
How did you copy and paste the layers?
In the QGIS GUI or in the text editor direclty in the XML file? If the
latter, then this might be the reason for you troubles. Each layer in
QGIS is identified with unique ids. If you copy/paste directly in the
XML structure of a .qgs file, you are also duplicating these unique ids,
which might explain your troubles.
You know, if all you want is to filter by year, you don't need a layer
for each year, but you can have a single layer and create a rule for
each year. Rules can be turned on and off just like layers.
Or you use the QGIS time manager to loop through the years.

About bug tracker:
What troubles do you have with the bug tracker? Why is it difficult for
you to access? The correct address is https://issues.qgis.org/ - you
need an OSGEO login or an OpenID. All information is at
http://www.qgis.org/en/site/getinvolved/development/bugreporting.html#qgis-bugreporting
If you don't have an OSGEO account, you first have to ask for a Mantra.
This is a measurment against spammers - because OSGEO mailing lists were
abused by spammers. You first have to prove that you are really an
indiviual person interested in OSGEO.
Please be a bit more precise why you find the QGIS bug tracker difficult
to access.
Hope this helps,
Andreas

Hello,
Excuse me for posting to the developers list, as I am not a QGIS developer, but
the bug tracker seems to be even more difficult to access.
I'd like to call your attention a problem present at least since 2.16, and
which is still there in 2.18.10 :
I have an approximately 50 years period of data to be presented geographically,
and each year's corresponding layer should be able to be turned on/off. I
created the first year's layer, then tried to copy+paste it, and modify the
year in each layer's rule. The problem is that the pasted layers don't seem to
be independent. It looks like they are created by some kind of shallow copy,
thus sharing some of their attributes and data fields, like visibility for
example.
Please correct this, or give me some hint if I make something wrong. Thanks in
advance,
Peter
