Problem with altitude setting

[Bulva]

The problem is that the controller gives me QNH based on the metar and it is ATIS compliant. However, when I fly and stabilize the desired altitude after taking QNH into account, I always get the attention that I am too low (or too high) 300 feet. It looks like I always have to set the altimeter to 2992 regardless of the metar. This situation occurs both at 3500ft and 10000ft.

Sorry, I don't have a log file with the problem described.
If there is no simple answer to my problem, I will try to attach a file from the flight.

You have to switch your QNH from atis (when on the ground) to standard (29.92 or 1013) when passing the transition level when climbing or decending.
The transition level can be adjusted in 124thATC.

Thank you.
"The transition level can be adjusted in 124thATC"

I'm an idiot.
I forgot about it completely.

I still have a height problem.
Appears every time I go below transition level.
The controller gives me the required height and Altimeter pressure, I set the pressure on the altimeter, then set the prescribed height. And the controller always screams that I am too high 200 ft. (or 300,400...)
???
Where's the mistake ???
  The second problem (I use ASXP) - and the ATC very often assigns to me a take-off or landing to runway that is completely different than ATIS indicates.
I don't understand this either, where is the error ????

Unfortunately, I did not register this error in the file.

Please help.

I solved problem # 1 (my fault).
Problem # 2 not solved.
