Geopak SS4 Profile Export to Native

Hello,

I am working in Geopak SS4 and have created an alignment and profile. The profile is named and set to active. However, it is not saving to the native .gpk file which I need to print the profile onto sheets. I've tried using the "Export to Native" button but it gives me an error saying "The element is in a model that is not allowed by this tool." I am in the Multi-Model views window. I've tried changing it to Default-2D, but it switches back to multi-model when I open the profile. Is there a reason this isn't working, or is there another way to print the profile with Geopak SS4? 

Thanks,

Andi
