KNX configuration of shutters - 3 shutters do not work, same different actuators

Hi Everyone,
I’m pretty new in the home-assistant family.
So far a lot is working properly, but I do have the problem, that 3 shutters in my house are not working with home assistant.
If I’m moving them via KNX switch everything is working. If I’m trying to move with HA, I do not get a reply of the KNX shutter actuator in group monitor from HA.
Other shutters on the same actuator are working properly. At this shutters, which are working I could see a response from the actuator in group monitor at HA.
I copied the configuration from working shutters and edited the group adresses accordingly, but no change of the behaviour of the shutters which are not working.
Could anyone support?
Thanks.
Best regards,
Markus
