When you attach to the activation key multiple subscriptions which contains same product, for example Red Hat Enterprise Linux Server 7, then you will see 2x same repositories in Repository Sets tab.

If you attach 3 subscriptions, then 3x same repositories

Version-Release number of selected component (if applicable):
Satellite 6.3.2

How reproducible:
Every time.

Steps to Reproduce:
1. Create activation key
2. Attach subscription 1 with product Red Hat Enterprise Linux Server
3. Attach subscription 2 with product Red Hat Enterprise Linux Server
4. Click on Repository Sets

Additional info:

Even though there are multiple records shown they are all updating at once, so there is only problem in view, which confusing the customers, but records are changed on all of them when applied on just one of them.
