glTF Exporter texture is not the same

I used this plugin for exporting uasset to .gltf or .glb files.
It worked successfully except for the issue that exported texture is not the same as the one in UE4.
So I tested some uassets and figured out when Emissive Texture is connected to other parameters like scalar, the exported texture is not the same.
I am not sure if the cause is because of Emissive Texture. Any advice or solution would be appreciated a lot. Thanks.

Same problem here, did you solve it?
