Vector lines turn to filled compound paths from Fresco to Illustrator

I just got Illustrator for iPad and I was excited to streamline my workflow now that Fresco can open directly into Illustrator as vector art. I have many Fresco vector drawings that I wanted to clean up, change line thickness, etc.

However, my workflow is impeded, and lengthened, by all vector lines turning into filled compound paths. In some cases, even when I release the compound path, remove the fill, and add a stroke to make it a single line path, I still cannot properly retain my lines because they were turned into a shape.

Is there a way to make my lines appear as line paths instead of compound paths that require more work? If not, can this be fixed or implemented?
