webUI raises error for "operatting system" tab on submitting the "new host" form for first time even when all entities are properly associated.

Description of problem:
I was trying to provision a new host and as soon as I submitted the new host form, webUI highlighted "operating system" tab with 'red' border but no error on webUI. However, production.log says:

] [I] Failed to save: Medium can't be blank

Please note that media was associated. Please see the screenshot.

Also, above should be an error statement not "Info".

if you re-associate the media, then provisioning works fine.

Version-Release number of selected component (if applicable):
sat6.2 beta snap9.2

How reproducible:


Steps to Reproduce:
1. provision a new host
2.
3.

Actual results:
webUI raises error for "operatting system" tab on submitting the "new host" form for first time even when all entities are properly associated.

Expected results:
1. UI should n't raise any error when media is properly associated.
2. In case of error, error should be thrown on webUI
3. error in production.log shouldn't be a info statement. It should be an error log

] [I] Failed to save: Medium can't be blank


Additional info:
on re-submitting the same form again works, but not for first time.
