Only half of map/layer loads in Dashboard map...?

I have several different dashboards with different hosted feature layers.  Often, when the dashboard is opened, only half of the map/layer loads.  Anybody have any idea why this is?

Not sure how to solve your specific question but in general when dealing with more than one kind of geo data I find it useful to use MapBox. You can add layer upon layer of stuff and then make that map the map for your viz. Then I just use my most relevant one set of geo data in the Tableau view so I don't have to struggle to make it handle two.
