Super strange problem!

I can’t select some of my text objects!!
They are all in the same layer, I’ve inactivated all other layers, but when clicking the keyframe it selects 5 out of 9 textfields… And when clicking the (non selected) textfields nothing happens, what is wrong??

The layer is not locked since I still can change the other textfields… I can’t delete them or anything! If they where converted to MovieClips I know I could change them via the object library, but is there a similar way to select objects that aren’t in the list?

Please help!!
