Can’t Complete Mission

I am on a mission called “Open Your Eyes” on stage 7/7 which is called “Land The Ender.” The objective is telling me to “Flip Trick and Grind in one sequence.” No matter how many times I do exactly what it is asking me to do the objective never gets completed and I have been working on it the past couple days to no avail. I have done exactly what it says hundreds of times now but it is completely bugged and won’t complete. All other missions are locked until I complete it so it is really hindering my progress and I would love to get it fixed
