Here's the problem with trying to fix the base before the release. The release is allowing you to prop up your upper body weight, thereby not requiring a solid base to counterbalance your upper body weight. You see, the lower leg IS the counterbalance. Since you don't rely on your lower leg to balance the upper body, it is slipping back.
You need to start weaning yourself of that propping up crest release. It will REQUIRE you to bring that lower leg back up to the girth. The further forward your upper body is, the further forward your lower leg must be to counterbalance the upper body.
Get into your jumping position and hold your arms out like an airplane. Move your lower leg forward until you can maintain that position with the arms out. Then (on a lungeline?) walk, then trot, then canter until that lower leg stays where it needs to be to maintain that position without your hands on the neck.
Then try jumping a grid where you can ride through with no reins. Put your arms out as you jump.
This will help develop that strong, base you are looking for.
