Controller paddles acc/brake activating push to talk voice (not radio) - N

Never noticed it until yesterday that the controller paddles acc/brake are activating push to talk voice (not radio) which is only bound to N as default.

I thought it was an after 8pm storm usual glitch of some kind and napped came back and it was the same, napped again and was ok. 
Signed on today and it's now doing it again. I didn't check if it was happening straight away but been about 30 mins or so since entering the city and noticed it activating when accelerating or braking.

Have flown out the city and back and it is now ok. Will monitor any actions/key presses that may trigger the bug and update if need be.
So many things make this server one of the best and decent controller support really does set it above most

Controller I use is Razer Wolverine V2
Thanks.

Update - Also happened out of a vehicle too so the aim/lock and punch etc. via paddles.

I tried with some random controller I have and didn't experience this. None of my controller buttons even seem to activate PTT.

Does anyone else have this issue or do we think it's controller/player specific?
