[homekit] Items not visible in home app when using more than 1 bridge

[IonasElate]

System:
openHAB 5.0.0
Build #4482
in a docker environment on a synology nas (DS 7.2)

• also true for the current stable version of OH 4.

For a few months now my homekit items are gone that i created for the additional bridges.
The log tells me that the items are created (bridge 2 and 3) but i do not see them in the homekit app.
These are mainly temperature and other measurements and i already checked in the overview of all temperatures that they are not hidden in any room.
