Bucket priority on Admin UI

The new UI contains a bucket priority inplace of previous MRW code.

1. It would be nice to have some explanation on the UI itself of what the prioritization implies.
2.Options for Bucket priority are listed as 2 to 8, it should be changes to 1 to X, bucket numbers can range from 1 to any ( 10 typical or higher), this number 2 to 8 does not tie in with this.
3. For singularly created bucket, my current bucket priority is 3 - which is incorrect, since it is the only bucket present on the cluster. [see attached screenshot]
