Some strange things are happening with the submission forms…
Add Book: when clicking the Language button, almost all the fields disappear.
Add Book+Edition: when clicking the Add Credit button in the Edition part, a bunch of fields get duplicated.
This is happening on two different browsers (Chrome & DDG).
Sorry about that. I’ll get this corrected soon, definitely today.
This sounds like what I was experiencing with BUUUUG! What's going on with adding an author to a Book?
Good use for the raw edit 
Exactly, fixing that BUUUUG inadvertently created this new bug. It’s fixed now. And I’m looking at ways to test the form for thoroughly.
Awesome. Thanks. 
I tried once. Not my cup of tea.
