I think I know what’s going on.
When you say that you closed the help folder, you actually only closed one of the notes. That’s what I understand from the X button you described.
What @ryanjamurphy meant with “the x in the top bar” is the main window close button: the red x circle on the top left (Mac) or the x on the top right (Windows).
Please try these steps:
- With the help vault open, go to
Open another vault and open the vault you want Obsidian to open to.
- Close the help vault by clicking the main window close button.
- Go to
Open another vault again (this time from your own vault) and remove the help vault from the sidebar on the left, by clicking the “x” to the right of its name.
- Quit Obsidian (
Cmd+Q Mac / Alt+F4 Win)
- Restart Obsidian
If this doesn’t work, let us know.
