Trimming won’t work after purchasing that feature???

I like the functionality of the rest of the app, but I bought this specifically for the trimming feature. I will change rating to 5 STARS if and when the developer fixes this problem for me. It even says in the app settings that I have purchased that feature, but both TRIMMING and DELETE are greyed out and unusable.
