Packaging warnings

I’ve been getting packaging warnings for a while about the same issue. My projects still package but it’s irritating that it keeps showing up. It doesn’t matter what project, or if I migrate the project to a blank one, or even start a brand new one. Some time ago I downloaded some epic content “tropical ocean tool” in some long lost project that’s since been deleted. But it must have changed something on the engine. I’ve tried migrating projects, and deleted the ddc, but it still shows up. Any ideas?
