Hello,
thank you for all the details.
To find the issue we will need to verify the last thing as I written in previous post.
I recommend to turn all GeoLink features off and then try only a stabilisation mode for several minutes. Will it work properly - will helicopter return always to horizontal position?
Or will it tilt to some side after several minutes?
It is very likely that there is not problem with GeoLink at all but if unit is disturbed and can't obtain correct horizontal position all GeoLink features, all stabilisation modes and Rescue will not work properly.
In that case possible solution can be found here:

Can you also take a photo of how GeoLink is mounted at the helicopter?
Are these two different helicopters or one?
