Problem with Unreal Studio and Datasmith

I started a new project to test the beta of Unreal Studio, and so far I’m very impressed. Datasmith is fantastic, but I’ve been having a problem and I’m not sure if I’m doing something wrong or it’s a bug. Whenever I use the reimport feature for the Datasmith file, all the assets are properly updated, but they loose all the materials that I applied to them before reimporting the Datasmith file. I would really appreciate a workaround for this, as it can slow my work significantly. Thanks in advance.
