Soft-rejection for an issue that appears only in the review process

i got a soft rejection for my first WordPress Theme and it was because of an issue in my archive title I use the default the_archive_title(). I tested the title and it work perfectly.
Do you have any advice ?

Who is your reviewer ?

I got this issue from 2 reviewers : LoveThemes and pasqualevitiello. I didn’t understand the error because in my theme test all the titles match to the slug. Do you have any idea about this i problem. This is the only problem i got for now
