It's possible that this is already fixed in R2. We are just about to release a new version of Impression that will be available to Subscription customers of AutoCAD, AutoCAD Architecture, AutoCAD Civil 3D, AutoCAD Map 3D, AutoCAD MEP, AutoCAD Revit Architecture Suite, AutoCAD Revit MEP Suite, AutoCAD Revit Structure Suite, Revit Architecture Revit MEP, and Revit Structure.
If you are on Subscription for any of those applications, you will be able to download Impression 2 from the Subscription Center shortly and can give it a try.
thanks,
