Unable to save Access Settings in Contact Group

CMK version: 2.4.0p5.cre
OS version: Ubuntu 22.04.5

Error message:no Error Message

Hi,
in a Contact Group I am not able to give this Group access to a Nagvis Map.
If I check the ckeckbox of a Map, which i want to give access and save it, the checkbox is unchecked when I open the Contact group again.

This happens to all Maps in the Contact group.

I check all checkboxes and click save:
nagvis1

reopen the contact group:

Thank you for your help

I have the same with 2.1.0p5.cre (3 minors lower) when I want to edit the all contact group.

However, when I create a new contact group the checkboxes remain checked.

So I guess you can’t change the all contact group and this is a funny way of showing that?

it is the same on a new created contact group or on o contact group that exists.
I can not save the “Access to Nagvis Maps”- settings

Can anyone confirm this on version 2.4.0p5.cre?
Or is it just a problem on our configuration of nagvis or checkmk?
