SSO groups not added to User

SSO
1

Hi,

iam hosting discourse on my server.
For SSO i use Keycloak in combination with discourse-sso-oidc-bridge.
User creation, role assignment and all other features are working except the add_groups, groups and remove_groups values. The users will not be added to the defined groups, but with activated sso overrides groups the user will be removed from all other groups.

I´ve created the groups in discourse before i logged in over SSO.
I seems that discourse gets all required parameters (see below):

Do the exampleGroup and test groups exist with those names?

yes i created this groups in Discourse.
The names are equal.

Its also very interesting that if the testUser is a member of the group exampleGroup in Discourse he will be removed from this group after the login (In groups variable the exampleGroup is available in this time).
It seems that Discourse ignores the defined groups in variable groups.

Is there any criteria for the names of the groups?
