Frame problems, help

I was doing an event so that my character will change animation when pressing a button, what happens is that when I release it, my character will be as it is in the image for a few seconds and then it changes animation, it does not affect much but I don’t want my character to appear for a few seconds under the ground

Does the character pop up to ground level after a few seconds? And for the same animation frame?

If no for the last question, then I’d suggest you check your hit boxes, and make sure the bottom part of the hit box is under the characters feet for all frames. If the hitboxes are fine, then we’ll look at other things that could be causing it.
