Failover object missing

I've found that we suffer from this issue with a couple of our v11.4.1 LTM appliances. https://devcentral.f5.com/questions/failover-object-missing-in-traffic-group

 

I'd like to add the missing objects to the failover list, but none of the links work anymore. Can someone advise on how I can acheive this?

 

Thanks
