Page attributes that are greyed out in HCM Design Studio but indicate previous changes

We are reviewing some of our Manager Self Service pages and found a contradiction in the Request A Position Change page level rules that causes the Department field to display when we do not want it to.

What's strange is the Department field doesn't seem to be an attribute that can be changed in HCM Design Studio as it is greyed out, but it also has a blue dot next to it indicating that it was already changed.

I've never seen this. Could it be related to my security or could these rules have been created during implementation and somehow locked down after?
