This step model behaves quite rarely, if you select it in altium pressing over it (in 3d mode), then you can see the image, if not it appears as blue box

How can i fix it?

Thank you in advance!

Re-posting now since I couldn't post yesterday due to a strange bug.

The model is just created like that, with a blue sheet covering the top surface. I fixed it in SolidWorks:
