Help with controlling bottom side English

I’ve only been playing about 2 1/2 years. I took the slow approach to learning how to shoot and started with center ball, no spin shots for the first almost year of playing. Once I felt comfortable, I slowly started to incorporate English over time but have struggled specifically with controlling bottom left and bottom right.

Top or middle right and left I feel fairly comfortable with. Bottom backspin or draw is also comfortable.

Something weird happens when I try to put bottom left or right. I feel like I can’t control my aim, and the object ball never goes exactly where I imagine it will. I’ve tried low and high deflection shafts and still the same result.

I also tend to struggle shooting with low in general when the cue ball and object ball are far apart from each other. It’s like the bottom makes it harder for me to be as precise where I am aiming.

Any advice?
