SK-TDA4VM: CCS losses the expressions value

Tool/software:

Hi,

I am debugging my code on the MCU_R5F and try to read out the expressions value. However the values from one instruction to another are disappearing. I will attach two screenshots:

Here the first expression has value (pCfgPtr)

At the next expression the value disappears.

CCS  Version: 12.5.0.00007

Regards
