Variable status bit in internal variables

Hi! I'm trying to read the status bits of the variables but I can't get some of them.

The configuration I have in Service engine settings (zenon Supervisor) and Project setting - compiling (zenon Logic) is as follows:

I have “State/Timestamp for Intern Driver variables” enabled - Yes.
Allocate status bits for variables having properties - Yes
Embed symbols of all variables - Yes
Keep case of embedded symbols - Yes

Compiling

I have tried to set and get the values of bits M1-M8 (with VSIGetBit and VSISetBit) and I have succeeded, but when I try to get the values of WR_SUC and WR_ACK while changing the variable values in zenon runtime (service engine), I get no changes in these bits.

I also get the time and date with VSIGetDate and VSIGetTime.

I do all this in online (connection) in zenon logic and the part of the code and the part of the code that is not working correctly is as follows:

As I understood it, with the configuration I have I could read all the status bits of the internal variable. Is there something missing in my configuration or in the code?
