2.6.1 - Autogain saving troubles

Hello all.

I seem to have some toubles with autogain settings writting to the track file in new 2.6.1 update :

I do match level of all my tracks with autogain values while beatgriding, so after finished, I click the "lock" button (make autogain knob disappear) so autogain & beatgrid should be fixed & saved with track.

this worked with 2.6

however from 2.6.1, the Autogain value that I input manually, is not saved. It always return to the Traktor initially "analysed autogain value"

(very shitty analysis BTW, always applying positive gain, when MP3 or WAV already peak at 0dBFS...)

When I load the track again. Even with the lock function ON, applied autogain is the one that was analysed, not the I inputed and normally saved with track...

I also cannot Edit the "autogain tab" in the track properties. Case seems to be locked.

Does anybody have any clue about this case ?

I don't want to be tied to Traktor awful level analysis....

Thanks for your answers !
