MeshCollider Shows that Mesh is Off

When I save a .blend file directly into Unity from Blender, my character is added. However, when I add a mesh collider to my object and specify my mesh it shows that the mesh is rotated 90 degrees and scaled up from what it should be.

Picture of what I mean: Screenshot - 1808ab28daff916dd571f42a05c605e6 - Gyazo and another one: Screenshot - 66a6b9bda1e1bb55183cae2e565dde7c - Gyazo

I have also tried rotating my character in blender and re-saving it, but it does not fix it.

Is there any way to solve this problem? Any help would be very appreciated!

Hi

Did you try to save the file elsewhere and import it to unity assets later.
