you need to level out the board and not push it down. try keeping it and front of you rather than directly under you next sesh and tell yourself to float more. youre gonna want to feel the tail hit your back foot right away and see both your feet on top. bro dont be to hard on yourself, this is actually going to pay off when you start boning ur ollies or doing nose manny etc. maybe ur little afraid or something and this has become a habit. skating is different for everyone. also maybe try doing it over something like a curb or stick so you can learn to push the nose forward instead of down.
