QG8 PTB0 looks like PTA4

I am running the DEMO9S08QG8 board  I set all my inputs and output the way that I want them using the Processor Expert as a KBI.  I set PTB0 to an input (KBI) that is driven by 100 ohm output resistant source and PTB0 looks like PTA4 (the debug data) with a some of the real signal?  If I get rid of the input it look almost the same as PTA4.  It looks high impedance between PTA4 and PTB0 like 2Mohm  and all the corners are rounded.

 

How do I get PTB0 to not follow PTA4 so I can use PTB0.
