Can't add a doc because already exists, can't actually use it

[ellisd23]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I try to add “Documentation | FullCalendar” as a doc. It says it already exists. It doesn’t show it as a selectable doc in the dropdown though. Cursor seems to sometimes only show the docs I’ve explicitly added, and sometimes it shows what seems like a bunch of docs that are added by default. But 99% of the time it just shows the ones I’ve added.

Steps to Reproduce

See above

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Version: 1.4.5 (user setup)
VSCode Version: 1.99.3

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, it’s already in our documentation repository, so you don’t need to add it again.

I understand that. What I’m saying is it doesn’t show in my list of docs:

Sometimes this list is populated with dozens or hundreds of built-in documentation, but most of the time it only has the ones I’ve manually added.

The “FullCalendar 2” one I added there just because I couldn’t get it to let me add “FullCalendar” and it also wouldn’t let me select the built-in one.

Just start typing and it should appear in the documentation list.
