OSPFv3 use RID to run and build LSDB. The interface addressing is just information carried by protocol. This is oposite to OSFPv2 and very similiar to ISIS (IPv4). So this can be a reason of working OSPFv3 and not working RIPng.
In your case let's try to manualy assigne address to link and do not use eui-64 automagic.
