Major tilemap issue

I have a small issue with the Tilemap object every time I import the json file and the atlas image the object isnt visible but it has the correct dimensions. I have everything correct on tiled with orthogonal and embedding the atlas into the map. If anyone has the same experience how did you fix it because this bug is holding me back.

Hi, are you using Tiled? If so, it could be the version you are using, as you can read here: [Solved] Tilemap Collision Mask creates only the outline of the tilemap size
