As Donutz said, in this case video will help a ton (even more than normal).
The only real way to kick a bad habit in your stance is to video it, see exactly what's causing it, then focus on it non stop until you force it to click. Otherwise we're all just guessing.
Fair warning, even after figuring out what's going wrong, it'll take time. Bad habits suck to get rid of, but it's just one of those things where you'll have to remind your 500 times until it stops becoming a habit.
One quick tip an old freestyle coach gave me, once you do figure out what's going wrong in your stance (either by yourself or if you post a video here we can help), pretend you're on camera 24/7. This will force you to focus on your style and technique instead of zoning out and going back to old habits.
