LEM Version # in console vs. on client devices

Morning all -

I am auditing which devices within our KACE appliances have LEM agents installed. I am also making note of which versions they are running on. Within the LEM in my Node's list all of my Windows machines are showing 6.3.1 but in my report from KACE, which i am confirming is correct once i check the devices manually, are in fact all on older versions with the exception of about 20% of them. Does this Version column represent something different?
