Barry, thanks for the tip. I tried a test of removing our libraries and only having the 21 Graphisoft Library, no fix to the issue. I then deleted all items in the embeded library in case of a conflict, including older 19 created stairs. Still no luck on the stair Floor Plan Display or getting the numbering back in the menu.
Edit: I also opened a clean version of our 19 template without any drawing in it and removed all the missing libraries and just loaded the GS 21 one. Still the same issues.
Is there just a problem between 19 and 21 where a full template rebuild is required?
