Slingshotting Cows (Entities crammed slingshot)

In my cow farm, the cows fly forward and backwards from where they’re standing out and back. I tried to interact the cow but I am unable to interact with the cow. This appears to be a visual glitch. I have experienced this with a Piglin Goldfarm as well, it seems entities crammed into a small block result in them shooting from that block and outwards, but then it comes back. I’ve attached a picture showing the cows.

in addition to this, I had a minecart stuck on a rail under a pumpkin and melon farm that I was unable to interact with. I destroyed the block and the rail under the minecart but it stayed there as if it was an invisible block, but I couldn’t place a block under it.

 

edit I can’t seem to attach photos.
