Mate controller

Hello everyone, friends. I want to create an animation using the mate controller. But the relationships and directions I set are constantly changing, out of nowhere. I've been trying for days, there is nothing I haven't tried. But each time it keeps changing and going astray on its own. I recorded the video. I didn't cut the video, maybe there is something I missed and you can see it. I explained everything in the video. Please take a few minutes and find a solution to my problem. I will be grateful....
