OSPFv3 CCR2116 v7.8

Hi, I bought CCR2116 recently and it is connected to Aruba 2930m with OSPF/OSPFv3, and just noticed that with every reboot of the switch for firmware update etc, the OSPFv3 will need an ‘instance disable/enable’ in order to work, this doesn’t happen with OSPFv2.
my question is this a known bug or ‘feature’?

thank you.
