Gymnasts free hips with grips

[craizygymlvl7]

I just moved up to level 7 and only got grips now, and all my skills are way more consistent, so I'm happy but theres a problem, my free hip which was my best neatest and highest angle skill isnt transitioning well w grips and my hands keep getting stuck behind the bar or my grips shift and it messes up the rest of my routine
My next comp is soon, so any advice would be fab thx
