Imported Models Missing UV Channels

Howdy folks!

I seem to be running into a strange issue with imported meshes missing UV channels.

I’m using the Blender to Unreal add-on and on models that have more than 3 UV channels, the last channel doesn’t seem to come through the export.
But if I import the FBX that is generated after import back into Blender, all the channels are there.

For example, this Skeletal Mesh has 5. Body, face, mouth, a hairband, and a hair bit on top.

But the top hair is on the 5th channel, which seems to not appear after exporting.

I haven’t done super extensive troubleshooting, but it might be something with Skeletal Meshes. Static Mesh has 7 and they all come through.

As far as I can tell, there isn’t any import or export settings that would erase or skip UV channels?
But any insight on the matter would be much appreciated.
