Cannot load color profile (greyed out)

I am trying to load an .icc color profile from my lab, but when I can't select it: it's greyed out. Not sure what I'm doing wrong. All other profiles in there are also greyed out.

I copied the .icc file to Library > ColorSync > Profiles. When in PS, I go to Edit > Color Settings > Load. If I try to load the profile via View > Proof Setup > Custom > Load, I have the same problem.

I'm on a deadline and need to soft proof, so any help is greatly appreciated.

MacPro, MacOs Sierra 10.12.6, PS CC 2018

Thanks!
