Can't Delete Custom TSV From Project

I have a custom time-scaled value attribute on the project object, which I want to delete. When I try I get the attached message.

It's not used in any portlets - I just added it to the project edit page, project list view and nowhere else; I have removed it from both of these but can't get rid of the attribute itself.

Version 12.1.3.

Any suggestions?
