Help with weird button

Hi everyone…

I´m asking your help for a problem that might have a simple resolution.
I´ve created some animations with mc_tween2 but i can´t make my buttons that are inside a movie clip to work. I´ve tried by transforming a shape to button and ive tried too transforming to movie clip and call for is instance name to animate it. I´m attaching the fla for you to help me solve this problem with the best way.

ps. the buttons that doesnt work are in frame 2 in the bottom (“clientes”), you need to click in first frame logo to get there.

Thanks to all that help!
