Motorola Atrix 4G :: Different Incoming Call Screens?

Since I got my Atrix about two months ago, I have had several issues that I have seen posted and am still awaiting a fix. Like horrible call signal when iPhone has no problem, security lock timer, voice quality from my handset, but I have not read about this other one with the Incoming Call. This issue is very random for me, but when people call me, usually I get their image in the middle and what looks like the lock screen, with one bar on left and right that can be swiped to answer or hang up. This is the screen that I get maybe 75% of the time, but every so often I get another Incoming call screen that doesn't have the bars that swipe, but at the very bottom it has two large buttons, a green one to answer and a red one to ignore. I know not a big deal, you either swipe or press a button right? Well it also affects the ringtone, when I get the slider buttons, the ringtones work fine, but when I get the buttons, it uses the original default ringtone, not even the default ringtone I have setup on the phone. I don't have any other dialer or call log app installed, I just set up my ringtones in settings and choosing individual users. Anyways, I like the button screen dialer, better than the default swipe one, but is there a way I could set a default and not get different incoming call screens.
