Loadpull Simulation issue using portAdapter and the inherent Loadpull option within HB analysis setup form

Hi,

I have been trying to use the portAdapter from the rfExamples lib to sweep my load impedance. I run into issues there. Please check the image below :

For gamme=0.6, and phase=90deg, the output log shows that I have neg resistance at the portAdapter. I would like to understand what is going wrong.

These are the Properties form of all the instances. 

Since I encountered issues with the portAdapter and since portAdapter is really not necessary for HB simulations, I thought I will try the Loadpull option within the HB analysis setup form.

So my schematic looks like the following :

In this scenario when I run the simulation and look at the output log, I dnt see any negative resistance issues.

Can someone please help me on what's going on? 

Many thanks in advance.
