STWLC38 will not report Ptx correctly

Hello, 

I am trying to follow the Getting started with the STEVAL-WLC38RX document for FOD tuning attached. I am using STEVAL-WBC86TX, powered from a bench top PSU,  and STEVAL-WLC38RX, connected to an electronic load. Both are connected to the STMGUI. Following section 9.4 on page 60 of the above mentioned document. I have set all BPP FOD values to 0. 

When using the RX FOD tuning page, as per the document, the Prx value is being read correctly. However, the Ptx value is continuously reported as 1084. This value does not change despite and current draw increasing on the PSU.

Why is it that the Ptx value is not changing?

Kind regards,

Lewis
