2D Collider's Clipping

[reef island]

Does anybody think they could take a look at why this would happen?

I've got a 2D box collider on my charracter and a tilemap collider 2d and composite collider 2d on my tiles, and most of the time it works, it just seems in certain spots I shoot through the floor and get stuck??

edit: better demo video
