Description of problem:

This is only the case via provisioning template. When is try to provisions a new system.

After upgrade to Satellite 6.15 content source no longer shows registered through load balance but instead points to a specific capsule. 

Instead, if you try re-register a system already registered works as expected I mean showing the LB and not eventually capsule-fqdn

Steps to Reproduce:

1. Satellite - Capsule - Load Balancer

2. provisions a new system

3. Register the new system selecting a capsule

Actual behavior

When It try to register a new system select "any of the capsules" ,somehow ends up registered directly to the capsule and not show the LB 

Expected behavior:
When I provision a new host and I want register it, should be registered showing LB and no capsule FQDN.
