Got it (I think)
So I opened my 65151c01-f1 in Parteditor, changed the part number from c01 to c02, part 65141c02 to 65141c01, and painted it black. Here is the actual result:

(same for f2)
It looks correct in Ldview too
And I can search it in Ldcad

Also I removed the part 65141c02 from my library
