schema , witch is used by Mapnik's rendering process.
The most probable hypothesis is : some old nodes and old ways still
exists in 'OldNode' and 'OldWay' tables, with the "visible" status as
'true' instead of 'false'.
See the shema for reference:

My suggested solution:
Create a brand new collection of nodes with the position of "all
fantom nodes", and sending'them to the Tech tem of OSM. They'll be
able to run a query into the
'OldNode' and 'OldWay' tables and switch the "visible" status from
'true' to 'false'.
Don't do this. The rendering database doesn't have OldNode or OldWay
tables or a visible status. For that matter, the master apidb database
doesn't have those tables either, it has ways and currentways tables.
This is normally where I'd give a solution, but I don't have one. It's
an osm2pgsql bug, not a DB bug, but without a reproducible testcase and
verification that the bug happens on recent versions, it becomes a
significant effort to get anywhere.
