Health Dashboard - Views - Empty or blank view - Evolution View show up as blank

When using the HD Dashboard, evolution tiles or screens on the dashboard show up as blank.

Here is an example screenshot:

 

This issue can occur when you have customized the JSON files used by the HD Dashboard.

1. To re-mediate, check your customized *.json file for a section like

   "Evolutions":{
   "selectedApplicationCount":10
   },

2.   If you are missing this section, add it back into the *.json file, reload your HD dashboard, and the problem should be resolved.  

   It is generally a good idea to save a copy of the default *.json files as well as prior working version of the *.json files that you are modifying so as to refer to them later.
