Need to make "Skill" attribute mandatory in Content Sections

Summary:

Job Profiles-->unable to add Skills section in DFF we have created. Error is to make the Skill leading attribute mandatory.

Content (required):

As per SR updates, it says that Custom Content Sections has customization that used Skills template to not show the leading attributes(Skill field is leading Attribute for Skills Template) in UI in 21C.

Hence, we tried enabling the Mandatory Skill attribute through Page Composer but this also enables the fields for other Content Sections as well which not be the case. Why is "column skill" driving other sections fields?

Any idea how can we make this work?
