No, this is a different issues.
In 3.6 we added a feature to let the engine manage also the engine VM
itself; ovirt-ha-agent will pickup the latest engine VM configuration
from the OVF_STORE which is managed by the engine.
If something goes wrong, ovirt-ha-agent could fallback to the initial
(bootstrap time) vm.conf. This will normally happen till you add your
first regular storage domain and the engine imports the engine VM.
