There is some issue with your system. Ideally you should see bucket ID against an ATP group like this:
Please click on the configuration button and make the Bucket ID visible.
Similarly for Bucket configuration also you should see Bucket TS after Dist Key field:
Please click on the configuration button and make the Bucket TS visible.
This means you have not assigned Bucket ID to your ATP group. Please get this corrected and close this thread if you are able to do this.
