How to create a circle animation in Adobe Animate?

Question

Animation

In general, I'm trying to create a simple animation of png rotation in a circle. I created a time line for 80 frames, on every 10 frames I rotate the image by 22.5 degrees:

But when viewing it, I get this game:

That is, for some reason, the fifth key frame first returns to its original position, and then rotates by the required number of degrees counterclockwise , although it should be clockwise. What am I doing wrong? Thank you.
