One or two paragraph formats won't change fonts for me, no matter what I do

[Lew Yedwab, Resideo]

Updating a 4 year-old document. Need to change all fonts in the document to Arial and basic variations of Arial. 

Some paragraph formats in use in the document obediently change to Arial when I update them in Paragraph Designer, like "+ List" in the attached illustration. When I make the same change to "+ List 1", nothing happens. I've hit Apply and Update All and I'm certainly smart enough to select Remove Overrides. 

Does anyone know why the paragraph "+ List 1" refuses to update? 

Thanks!

There is a Color Character Format applied to the paragraph. It is likely applied to the entire paragraph. Try selecting the paragraph and apply Default Para Font to clear out the Character Format. You may have to reapply the + List 1 Paragraph Format.

In similar occasions reapplying the paragraph format helped.
