I am working on what will become a huge multi-page weld drawing. I have saved some common weld symbols into the design library. I started inserting the symbols into the drawing on different pages, and it was working fine, then all of a sudden I can't insert them any more. I get a warning dialogue box that states "FAVORITE WITH THIS NAME ALREADY EXISTS IN THE DOCUMENT"
I can copy and past existing weld symbols, but that's a bit of a PITA because you have to scroll back to some other page to find the symbol you want.
I have seen reference to this problem dating back to SW2011, but have not seen a fix for it.
