I made a cleaning cart in blender using quite a few Boolean modifiers.
Originally I had the same issue within blender, but after just messing around with the object I was able to fix it.
Now once I export the object as an FBX into UE4, it mysteriously “grows” a face over the handle area.
I have exported the cart with just one (1) receptacle and had no issues, but as soon as I shift D the receptacle part to the other side and join all three (3) objects I have this issue.
I have also unwrapped the UV’s multiple times and feel like they are at the most optimized they can be.
You can try applying all transforms. I think sometimes that helps.
I tried that, and had this issue. see photos
For some reason it is literally just one side. And like i stated once i Shift D the object I run into this error.
And I still get the same error once I bring it to UE4.

Check if the face is a quad or triangle, not an Ngon.
An easy check is to: editMode -> editFaces -> Select -> Select by Trait -> Select Faces by Sides -> set “Number of Vertices” to 4 -> set “type” to “Greater Than”
If the face is an Ngon, just knife tool across the elbow of the face (or select two vertices and “connect” them together.
