Tilemap not generating colliders

Unity 2019.3f1

I have added the Tilemap Collider 2D to the tilemap as seen below. I have a player object with a rigibody that falls right through. It also doesn’t seem like the editor window has the green outline that indicates a collider.
Could it be that it’s because I use a scriptable tile?

Thanks for reading.

I just tried with a single non scriptable sprite tile and collisions work. So I’m thinking it has to do with the tile being scriptable. Or because sprite mode is set to “multiple”.

Figured it out.

Had to set it in the GetTileData override

public override void GetTileData(Vector3Int location, ITilemap tilemap, ref TileData tileData)
  {
    tileData.colliderType = ColliderType.Sprite;
