I did a quick test of the ILS 28 approach in the 930 and it seemed to work fine. Locked on at the appropriate place and was on track to a normal landing all the way down.
Not sure if the issue is related to the Fenix 320 specifically or something else, but the ILS signal seems to be working as it should for that approach. You might run a quick approach using another aircraft and see if it still has the issue.
