SharePoint - Integrate List to Power BI - Visualize List - not showing all fields

I have several sharepoint list that I'd like to visualize with Power BI.  I'd like to use the Visualize List feature in Sharepoint as a quick way to build a simple dashboard within the list.  When I attempt to build the report only a few fields show up in the dataset.  One list it is the first 9 fields available, on the other it is a random 9.   Ironically, this morning I attempted the same thing that wasn't working for months and found all 25 fields in the dataset showing but when I started to edit the report it reverted back to the 9 that was originally provided.  Does anyone else have this issue or can help identify a solution.  

Details:

-SharePoint Tennent has Power BI integreation enabled

-I am running Power BI Pro

-I have full read/write access to the data
