OSPF V6 to V7 PTP not working?

Can some advise why OSPF PTP from V6 to V7 will not populate OSPF neighbor ?
In ip neighbors all devices are listed and can ping all the devices ip's ?

Thank you !
By looking at your config I noticed that I hadn't added
/routing ospf instance router id ?

for a start try to adjust your firewall to accept protocol 89 ospf on input chain on both of your router, because your firewall rules might try to drop OSPF and will not form adjacency no matter what you do or disable your firewall rule temporarily if it's in controlled environment or better yet export your config and hide sensitive and upload your config so that others might take a look on your issue
