Only last 2 button rollovers work..?!?!

i have 6 buttons. One by one i made the rollover state alpha=50% , down state =tint change , and i tried using hit and not using hit states.

after making these changes on button 1, I did “test scene” and the states worked. i added the same changes to all the buttons - positively nothing else - and now only the last two will work in “test scene”

however, when I do enable simple buttons, they all work as requested?!?

when I publish, last 2 work.

I’m on a mac, but it does the same thing on a pc when published.

Please help??
