I edited my post and it said "Vote Now?"

I just edited a post of mine and instead of saying "post now", it said "vote now". I know its nothing to moan about, but i thought i'd just let you guys know.

Sorry if this has already been posted/sorted etc. i just thought i'd bring it to your attention!

I just clicked edit on the above post and this time it just said save, so i dunno why it happened the other time. Anyway heres a print screen of what it said
