VFR airport zone transit problem

Hello,

With P3D V3.3.5, I encounter a VFR European airport zone transit problem.

It happens this way in my case. After transiting to the end of the airport CTR zone, I report "clear of the zone" and the controler simply goes <callsign> tower, "pass your message".
And no matter how many times I repeat myself, he will still say "pass your message". The only way to clear the problem is restart the program or just avoid the airport control zone.

Has anybody a solution to this problem ?

(It seems that this problem exists since several years and it was never corrected in the differents VoxATC versions.)
