For starters, disconnect your EmissiveColorMaps; if that causes the glowing to disappear, you’ve at least pinpointed the issue.
After that, dig deeper; perhaps, you can get the effect you’re going for by only connecting the R or the G or the B output pin into the Emissive Color pin individually. See below.
Without looking at your .png (or whatever type) texture files, there’s only so much we can suggest.
