In order to reproduce the bug:
Summon zombie dogs -> dismiss zombie dogs / remove your zombie dog skill -> save the templar -> templar avatar will have a green three in its level rectangle.

If you hire your own templar from town this bug will not occur and his level will be correctly displayed, so it only occurs in the quest.
