Revive 5.5.0 Campaign shows linked Zone, but not vice versa

[EdTGuy]

I just installed Revive 5.5.0
I've created a campaign, two banners a website and a zone. I linked the zone to the campaign. Under the Linked Zones tab of the campaign, it shows the website and zone under Linked Zones on the right side of the window; however, just under the "Linked Zones" header, it shows Linked: 0 Showing: 1. When I navigate to Zones and click on "Linked Banners" for that zone, nothing appears under the section "Campaigns linked to the zone:"

Is there some additional configuration I'm missing, to allow this campaign to be linked to this zone, so its banners can be displayed?

I resolved my issue. I had set up the zone for video, but did not did not set up my banner references to my videos correctly. Once I did that, the campaign was selectable to link to the zone.
