I'm making a mod that adds new birthsigns to Oblivion, but every time I add a sign, it shows up on the list in-game, but I can't select it and the information doesn't show up. Also, every time I try to delete a birthsign I made, it doesn't go away from the Birthsign Menu.
Any ideas how to fix this?

I guess I should have been more specific. I have tried the supposed "Bug-Fix" that is suggested on the Construction Set Wiki. I have put more than 15 copies of a birthsign in Oblivion and the signs are still not selectable. I am simply asking if there is another method to fix this glitch since the one suggested doesn't seem to work.

Anyways, thank you for your suggestion.
