Problem importing a tiff file.

Hello. I am having some problems and I hope someone can help me. I made a design for a snowboard top layer. The design was made in PS CC on a scale 1:1 165x35cm 300dpi. After I export from PS everything is good I send it to the printing company but when they load it into corel they can only see a long vector like triangle in which the design is visible the rest is white. This is the screenshot they sent to me. I've tried to export from photoshop with different settings like with compression,without compression same issue. Now I dont know if the problem is from my side or they have issues with corel.
