How do I prevent automatic Tilemap resize to layout?

Each time I create a new "TileMap" object, it's always resized to the layout of my project. First, I would simply double-click my layout, add a TileMap object, and then choose a small 32 x 32 png to import into the game. No matter the size of the file (since I also tried a 72 x 86 png), it's always resized to cover the layout, which takes up the whole screen. On top of this, the images don't display at all.

Has anyone dealt with this before, or do you have any suggestions? I'm not sure what went wrong.

The image of the tilemap doesn't show up when you create the object, you have to use the Tilemap Tab (should be by the layers tab by default) and paint out the tiles. It'll be easier to understand if you go to construct.net/en/make-games/manuals/construct-3/plugin-reference/tilemap

And it will always auto-size to be the layout size, but you can just resize it manually, so I don't see the big deal.

Thank you for the help. Now it makes sense why the Tilemap wasn't displaying before.
