Firepower not communicating with Vlan1

[00u18jg7x27DHjRMh5d7]

I have a new Firepower 1140 configuring with FMC. I am unable to ping or communicate it would seem with any device on Vlan 1. I cannot disable vlan 1 devices at this time do to some old architecture. I have a route facing inside, I can resolve DNS, I see devices on ARP table from other vlans that are on the Core nothing from Vlan 1. I can see the OSPF neighbor on firepower sent from core with no vlan 1 info. I can ping the Firepower vlan10 from the Core SW Vlan 1 but Firepower cannot ping Core. I receive health monitor warning no traffic on sub interface for vlan1. Running version 7.0.1, is there something I should be aware of that's blocking the traffic?

 I can see the OSPF neighbor on firepower sent from core with no vlan 1 info.<<- you run OSPF between FPR and CoreSW, but the CoreSW dont advertise the VLAN1 subnet to your FPR ?

UPDATE: OK so I have now determined that it will not communicate with devices that are not on the Native Vlan over the trunk. Once I swamped the native Vlan to 10 I can now talk to all Vlans ex V10
