Calisthenics Unity

Hi, I am struggling on getting past level 13 and i've been seeing this weird problem. The leg portion of the workout is great and i love doing it but i see that my right leg is becoming stronger than my left. i am able to do 2 pistol squats on the right while barely being able to do one on the left. idk if its just because i'm right sided or if i'm accidentally using my right leg too much in the exercises. please any suggestions to fix this would help

Surprisingly I'm right handed, but my left leg is stronger than my right one. It's easy to do it with pistol squats, if you know it's a strength issue and not flexibility, you do your pistol squats on your right one, and then do your pistol squat/s on the left one with a few extra assisted pistol squats, or something like that..

I can do 6 pistol squats on my right leg but 2 or 3 on my left leg and I think part of it is because I'm unstable on my left leg and have trouble balancing sometimes as I sprained my left ankle some time ago.
