Possible Animation Priority Problems?

ROBLOX Animation Editor was always a great tool for me and for most of people, since It did it's job really well. But now we have new one. I tried making animations using new, but guess what? I got weird error with animation when using it. (see below) https://gyazo.com/e1b7f08b167552c0cfbd88c643ea385d As you can see, I tried everything. I changed priorities, I locked body parts, I deleted value from Anima (the hands that have names of animations). Nothing seems to work for me. If you have time to help, please answer below. Sorry for posting unrelated thing here, since I didn't find any other active place with great support like this.
