Enchanters Sanctuary Bells

[SS-310]

So im trying to ring the three bells in the Enchanters Sanctuary cave on the north end of B3 but cant find the 3rd one as it appears to not exist.

I rang the bell next to the locked gun and the bell on the left side of the boss room behind the rock. I've walked through the cave three times now and the third doesnt exist. If you could tell where it is that'd be great, thanks
