OX App Suite Calendar resources on MacOS and iOS

I configured some resources (rooms, cars, etc) on OX App Suite. Users can find and book correctly these resources from OX App Suite web interface.

I also configured some Apple Calendar clients (Mac, iPhone and iPad) with MacOS and iOS and I noticed that I can find these resources trying to invite for example a Conference Room and I can also book it, but an exclamation point comes close the name of the booked resource and the resource isn’t really booked.

Resources booked from OX App Suite are shown correctly on Mac Calendar with green flag, but if I try to book a resource from there I have an exclamation point.

What’s the problem? Is this a known issue? What can I check?
