Classic Tween not working properly

[Rylance5FCE]

Hello, and I am having a problem about classic tween. The thing is that the when the animation is played, the classic tweened frames starts to glitch and it does not make a smooth tweening. I just turned off this setting called "Snap" to see if the tweened framed smoothens. But that did not work. It's actually a render problem.

you'll need to describe the problem better.  eg, it may be user error.  if you're tweening 500 pixels in 10 frames, that's not going to appear smooth.
