Unable to submit to Marketplace due to an engine bug.

Edit: Guessing someone here approved it for me since it was still sitting as ‘changes needed’, so THANK YOU!

I am unable to publish content to the Marketplace due to what appears to be a bug.

I have an asset pack (this is not my first) I have repeatedly attempted to submit to the Market. First I was told there was an issue with building lighting, but ALL the lighting in the level is dynamic. I none the less built the levels and lighting and resubmitted. I have “Force No Precomputed Lighting” set in world settings.

I was again told the lighting was an issue but could not figure out why. I resubmitted without making a single change.

Afterward, the person I was speaking to said this:
“The lighting error has been solved but there is still the issue that was stated previously of “1 asset with physical materials needs to be rebuilt.” when opening the project.”

I talked to people elsewhere and in the Unreal Source discord and am being told the above is a known engine issue and there is no way to resolve it.

I believe there is something weird going on between sending this pack to be published, and when the person on the other end (the person who is going over it from the Marketplace side) is opening the project. I am sure they are just as tired as I am over it because it’s been back and forth for three days now with I think five or six submissions being flagged as ‘changes needed’.

I am genuinely puzzled as to how to proceed, especially if this is a bug as it appears to be.

Here is a video showing the levels in question:
