On chrome, on the HIT catcher page, hit ctrl + shift + i (or right click -> inspect. It should open the console tab where you can write stuff. Write (without the quotation marks) "delete storage.watchers" and hit enter. It will delete every single watchers in HIT catcher (so make sure you are willing to remove them all). Then, you should no longer have the issue where you click "O" or "P" in HIT finder and it doesn't show up in HIT catcher.
