Hi, thank you for reporting the issue. Unfortunately I wasn't able to reproduce this.
Does this happen every time you try to create a collection using new web library? Is there any error or message showing up in the top-right corner? When this happen, do you see any error on browser console (to open console in Chrome, press cmd+option+J on macOS or ctrl+shift+J on Windows/Linux).
my apologies on this one, it seems to have worked when I refreshed the page a second time. getting a bit trigger-happy with these forum posts, sorry about that.
