Added a Sheet from Another Schematic

[PaulB]

I added a hierarchical sheet to my schematic which was a file copied from another schematic.

Some, but not all, of the symbols have anomalous reference designators, for example:

“R?-NOTFOUND-NOTFOUND-NOTFOUND-NOTFOUND-NOTFOUND-NOTFOUND-NOTFOUN?”

I can edit this reference to R?; but, when I duplicate this symbol, the new symbol has the same “NOTFOUND” reference.

Three questions:

1. What caused this?
2. Can I correct this?
3. Is this going to cause any problems later on with annotation, layout, BOM creation, etc?

FYI, after doing various things: saving, closing schema, annotating, etc. Duplicating the the symbol no longer gives the “NOTFOUND” reference.

5.0.0 is already quite outdated (And has a lot of bugs that are fixed in newer versions). The 5.0 series no longer receives updates (And even so you should at least be on 5.0.2!)

I suggest updating to 5.1.4 (warning user interface changes quite a bit but the underlying data structure is fully compatible)
