Sidechain keep disabling in fairlight page

Hi !!

I used sidechain in compressor to keep the music volume down when someone is talking on video, so I put sidechain on "send" mode at voice track and "listen" at music track, as I always did

but everytime I quit resolve and start it again, The sidechain does not work, and I see that a new instance of sidechain appear in the track, as the pic attached - the normal is to have just one instance of sidechain, right?

So I have to delete all the instances and clik in "send" button again, so it back to work... untill next resolve start, and even if I close the project only, not quit resolve when I open the project again, same issue.

I hoe that got fixed asap, cause I use a lot this feature.
Thank you

Now with b4, it doesn´t duplicate "side chain" indicator at channel like the before posted image... BUT the bug keep going... now when I quit and open DR again, sidechain disable and I must go to fairlight page, than just disable "listen.." button in the music track, than click to turn it on again...and it back to work...until next DR quit and back.

I love sidechain function a lot, so sad to have this bug lol

Is this on Windows or macOS? System spec? viewtopic.php?f=21&t=90190

Is this behaviour only with Flexi Bus mode Projects or are you able to reproduce in Fixed Bus mode?

Project Preferences > Fairlight > Audio Busing Mode

I have this issue in home and laptop as well (not tested at work, that I have a better PC)
Home config:
I´m using windows 10 Pro 64bits
Intel Core i7 950 24 Gb RAM
GTX 1060 6gb
Laptop:
Acer Helios Predator 32 Gb RAM
Intel Core i7 (9th genaration)
RTX 2060 6gb

I´m not using fixed Bus mode (in fact I have never seen this option, I never chacked that box, and don´t know what it does lol

both with Davinci Resolve Studio.

Problem started when changed to 17 beta. Before all was ok.

Will install beta6 and see if it keep happening and back here.
Thank you
