Unable to configure OSPF during ASA to FTD migration

[NetworkMonkey101]

I am attempting to migrate from ASA to FTD and need to complete the OSPF configuration manually. When creating the OSPF network the object on the FTD keeps stating invalid IP.. 

Current OSPF config 

New FTD OSPF config

Why is this erroring?

@NetworkMonkey101 you've configured a different subnet mask on the FTD (a /20), where as the ASA is using a /28 (255.255.255.240). Change the subnet mask on the FTD to a /28.

there is mismatch between IP in interface and network in ospf 
check the mask
