D&D 2024, trying to creat e new gear but won't allow to copy over and rename

[nightwebs2day]

In the past i would create a new gear or item. I would open "book", copy book back into the list then take the new "book" copy, rename and do as i please. now i can not copy the original "book" back to the list. any ideas what has changed over the past 2-3 days?

Try doing this in the Item list, not in the Book entry.
