C10 - GA : Additional Content Issue

Hi all,
I’m using C10.0.5.
Upgrade from C9.5 ran OK.
In the C10 Installer folder, I have an Additional Content sub folder when I found VST Sounds for GA & other instruments.
After install, I have few links in the C:\ProgramData\Steinberg\Content\Groove Agent\VST Sound still pointing to the installer additional content Groove Agent folder, like metronomic cinema for instance.

The issue : Library manager says it’s well registered when clicking etc… but these vstsound doesn’t appears either in GA5SE or GA4 when in C10.
List of the vstsounds with this issue here :

Everything else is OK.
