EVM430-FR6047: ADC Capture Shifted Amplitude

Greetings,

Today I set up the EVM430-FR6047. After a while I figured out the right parameters to get a good ADC Capture. But my waveforms have really high peaks. I think the problem is that my ADC Capture is shifted as shown below.
Does anybody have some suggestions how I can fix my waveforms ?

Thank you for helping :)
