Track Mute Params shifted?

Hello
After upgrading to OB 1.15 i can see in my Live sessions that my AnalogRytm is not responding the good way…
Apparently the parameters numbers have been shifted, for example : My clips with Trk1 Mute parameters are now on Trk3 Mute, Trk2 Mute became Trk5 Mute, etc… And of course there is no more automations on Trk1 and Trk2 Mute params.
This is really annoying because i have thousands of clips with Mute params…
Is this normal ? Is there a way to fix this ?
Thanks
