What's up with this 6V6?!

Been testing a bunch of tubes and I suspect there is a fault since the meter gives a slight reading on the first leakage test on my weston 981 tester.

Heater glows normal on first test, but glows like a light bulb as I switch to the next series of tests!

Seems to give an OK reading on emissions however.

It's a Sylvania 6v6gt
Any ideas? See photos.
