Tilemap/Composite is leaving a line after tile remove


I hava a grenade in my game. When it explodes, it deletes the sorrounding tiles.

But sometimes it leaves a line of collision and I can't find an solution for this.

I tried to delete the composite collider but when I did, the player got stuck when moving.

For future readers, I was able to fix this by going to the Tilemap object in the grid that used to contain the tiles I deleted and toggling the Tilemap Collider on and off. This also updated all physics outlines I had manually changed.
