Named Selections + Copy/Paste Issue

I use NamedSelections often, very very useful. I have a problem though. Sometimes I copy objects from one file to another, it then adds ‘copies’ of the objects to my named selections panel, its very confusing and is a pain. Is this a bug ? Or is there a way to stop this ?
ps, I name all my objects in every file, it helps with creating BOM tables and being organised when asked quick questions of quantities in meetings etc

Hi Miles -

Hi Wim, the issue seems to be if I have Make2d geometry in the file, I’ll keep poking away
