Wan-Link Manager shows wan down, but in reality its up

So like others have said, deleting and recreating might not be necessary, just saving the interface configuration without changes can fix some issues. With at least three of us having it work in the past. I think that should be noted in the accepted answer so people don't have to go through deleting and recreating and the side effects of that.

Also, you say you lose associated rules, but which rules are those and are they port-oriented rather than zone-oriented? That's one of the benefits of zones: you can change what ports are in what zones without affecting Firewall rules.

I had actually tried saving it but that did not yield any result.

And yes, the rules were associated with ports instead of Zones.
