TM1 security Group import Issue

[Avvu]

We have cognos 10.2.2 environment for Cognos BI and Tm1.
We have Tm1 security being imported from Cognos BI. So far Everything running smooth.
Recently we had to create few new groups to be imported to Tm1,while importing these new groups to TM1 it is throwing an error saying "Error adding the group".
But the group is getting added to the Tm1,But in the clientgroups cube it doesnot show the group's display name instead it shows CAM Id.

Can anyone help me on this?

We have found out that there is an issue with few of our rule files.

The issue is now resolved.
