press the record button and there's a D, then a loop symbol, then a P???

[Sareen]

when i opened up a session, I was able to record a keyboard part. Then right after when I made a new track to record another part...I click rec enable, then click the record button, and instead of flashing red like it's supposed to, a D shows up on the record button...click again and there's a loop symbol..click again and there's a P..then it just goes back to the regular, non-lighted up record button!

I've figured that those 3 things mean destructive recording, loop recording, and punch-in.........why do they keep popping up and not letting me record normally??????????
