ATC never gets silent (RShift+M)

[J13 Serenity]

Hello

Before the recent DCS open beta update, player could use R<profanity>f+M to make ATC and AWACS silent.
After the update, despite using RShift+M and getting on-screen indications, ATC still keeps talking.

This is a huge issue for me and my friends, because when flying in a big groups against numerous enemies (especially in FC3 airplanes), AWACS never stops declaring targets and never "shuts up".

Of course, we can turn down radio volume in sound options, but then all other audio messages, like "bingo fuel", "critical AoA" etc... become silent also.
Or when using tanker, all his replies become silent as well.

I am asking to fix this problem as fast as possible

Thank you

This should be fixed now in OB. Can you please confirm?
