Bug report: Patch Input/output revert to default

Hi

I am doing a sequence that will be used as a template for future episodes.

The sequence is using one 5.1 track and 1 stereo track, with 1 stereo main and 8 mono sub. I am using the patch input/output to send both tracks on the sub for future deliveries.

Everything work as expected except that when duplicating the sequence or creating a new one, I am loosing the previous assigned patch.

Step to reproduce:
Create a timeline with a single 5.1 track and a single stereo track.
Add 6 mono submix with the fairlight/Bus Format

Open the Patch input/ouput on the fairlight menu (Must be on the fairlight panel too)
Source: Track send
Destination: Submix return

Patch all of the track send (Audio 1-L to sub1 audio 1-r to sub 2....)

Duplicated the sequence and open it

Look at the patch, the patch did not follow on the duplicated sequence.
Return to the first sequence, and look at the patch, they have revert to default.

Tried it on Resolve 14.3, 15.0. on 2 differents Mac.

Thanks have a nice day
