You are beating your horse to the jump, putting your weight over it's shoulders before the take off. This makes it harder for the horse to clear the jump (not a problem when jumping small, but as the jumps get bigger it may cause issues).
You need to sit still on the approach, whether it is a single jump, a double, a bounce to a single stride, a 6 bar competition... (get my point? Haha) it doesn't matter. If you have a good rhythm into the jump, the horse will clear it. All you need to do is have a good canter, keep your leg on, look up and sit there. Let the jump come to you, not the other way around.
I fire my horse at jumps when stressed, I get in front of the movement and find it hard to keep balanced on the landing... whenever we have issues jumping it comes from this because it puts my horse off balance.
If you need something to focus on, look through the jump to the other side of it and count your canter strides up to four my instructor taught me that. He said if he ever doesn't know what to do when jumping, whether it be an EvA80 class (80cm jumps) or a 3* class, all he will do is sit still, look up, leg on, heels down and count.
