Describe the bug
When you create a new bookmark and leave the directory empty, if you attempt to open the bookmark afterwards you will get a message saying "Bookmark not found, recreating..." followed by a popup asking you to use a certificate installer.

To Reproduce
Steps to reproduce the behavior:

1. Got settings
2. Got to interface
3. Under the sidebar section go to bookmarks
4. Click Add Item
5. Give the bookmark a name (in my case specifically I gave the bookmark a name identical to an existing one)
6. Leave the directory blank and press create
7. Go back to the home page
8. Click on the new bookmark you created
9. See the error "Bookmark not found, recreating..."

Expected behavior
If a directory is invalid then this would ideally be checked at the time of creating the bookmark. The user should be prevented from creating a bookmark with an invalid directory.
