Can't align or merge models in Cura

Good Afternoon I am struggling with a project to make a simple coaster with a logo and name. I made the base in Solidworks then used a cavity to make the insert portion (which does not go all the way through. I have tried everything I can think of to align them and get them to merge properly in Cura (5.9.0). I even setup a new coordinate system at the very top point of the S on both models and made sure that was selected as the reference output when exporting. I have uploaded a picture of what the part looks like in Cura when I try to merge them, as well as when I have them both aligned at X0 Y0. 

Any help would be appreciated. I don't see any option to align origins and honestly I am not sure why the origins weren't already aligned.
