One arm KB press compared to Bench Press

Hello everyone,

Today I pressed the Bull Dog for the first time on the Right side.
I felt good and gave it a try and it went up,left side was a pretty easy clean but pressing was not possible yet.
Still I am wondering why my Bench Press hasn’t improved the way I improved with presses and snatches with KB’s what can be the reason behind this?
Could there be a weak link muscle that causes my Bench to not improve within my expectations.
My Bench is 110 kg 1 RPM,and my KB Press 40 kg Right Side and 36 kg Left for multiple reps.
