Problem identified

Have you ever noticed that /administrator/templates/atum/scss/vendor/bootstrap/_form.scss from line 18 to line 48 and /administrator/templates/atum/scss/blocks/_form.scss from line 78 to line 108 have the same styles?

The main file template.scss connects both of them and they are connected only in that file, so we can reduce one of those files.

Proposed solution

Delete styles from one of those files.
