I got an issue when i bridge two Cisco routers and one Cisco ASA using an original Network object. The OSPF on the routers mark ASA peer as dead after a dead timer expires in BROADCAST mode, but between two routers the OSPF works correctly.
Seems it is related to HELLO packet which is sent to multicast ip 224.0.0.5 which is not properly processed/returned back from ASA only.
However if i use Cisco L2 switch instead of Eve-ng Network object then the issue disappears.

I suggest that when ever you use more than 2 network devices, prefer to use Switch in between, that is best practice.

Try like

Router -----Siwtch----ASA
Router-------|

R!
