plugins – Post showed multiple times

I started to play with Tutor LMS plugins and till now all works fine, except for a annoying problem with the student profile page; the sublinks (like enrolled-courses, reviews, wishlist, etc.) are showed properly, but the main dashboard is replicated 3 times on the page (same problem with login page).
I played a bit around, but I’m not a WordPress expert; do you have any idea?

P.S. I’m using PopularFX theme v. 1.2.0 on WordPress 5.7.2

Thanks for your time,
Gianluca
