Trace A and B select the same waveform

Highlighted

Hi,

 

I am trying to read the phase shift in a series RC circuit.  I am using the 2-channel scope, I connect Channel A across the source, and Channel B across the resistor.  It all looks good, I see the two wave forms shifted by time. Now is where I have the problem...   On the scope, I right-click the Channel 1 trace  and "Select a Trace" and choose Channel A.  I then I right-click the Channel 2 trace  and "Select a Trace" and choose Channel B.  What happens is that the Channel trace 1 jumps off the first waveform and ALSO selects Channel B so that they are both selecting the same waveform and I cannot get them to separate.  No matter what I try, they both stay on the same waveform to I am unable to do  T2-T1.  I have attached a screenshot showing the issue.  

 

I verified this problem on both MultiSim 11 and 14.

 

Any ideas on what's going on?

It is not possible to select the same waveform in RC circuit you have to define the 2 channel scope first in order to trace the lines in correspondence.
