Sounds like you have all of your weight shifted to the front, like that it can't come up. Hard to say without seeing you though, but try to not put too much on your handlebars, you want to balance yourself on your footrests (and don't hang your foot into it, stand on the front part of your foot) and stay easy on the handles without loosing touch.
Some people even "pull" their handlebars a little bit upwards, depending on the bike u ride. The ZX should do it easily.
