 Permissions are only applied here when you create a group or click "Save and Overwrite Existing groups". 
 If these permissions were changed in administration after the application and group were created, you either have to go to that group and manually change the permissions, or you need to click "Save and Overwrite Existing groups". 
 Additionally, I have observed that permissions at a "group level" do not propagate to applications within that group in all cases. Especially if you have more than one application in that group, and you have to go through your groups' individual permission administration fly-outs from the pencil and double-check that the permissions are set there correctly. 
 This is immensely frustrating from an administrative standpoint, I have been unable to trust whether these permissions are set properly, it would be helpful if I was able to tick these permissions and say "apply to group and all applications within the group" on at least the group level. Or when setting these at the administrative site level, to tick to "exclude from stated groups applications or exclude stated groups". 
 When trying to raise this issue with Verint support previously, basically we were told it's working as intended. The problems with attempting to set these permissions en masse via API or otherwise can encounter timeouts and it's difficult to verify that they have properly applied. We tried various workarounds. 
 Ultimately you'll have to verify manually at present.
