Grouping problem with imported salesforce data

Hello, 

I am having trouble grouping individual fields on a visualization of mine and I believe it has something to do with how power bi is accessing my information from salesforce. When I right click on the fields I want to group, I don't have an option for a grouping button. I have not been able to get any of my DAX code to work with this data and I can't get the imported data to display in the power query editor. Is there a way I can group these data structures and is this due to how the data is being imported from Salesforce?

I've tried using this solution: Solved: Grouping visuals not working (no right-click menu) - Microsoft Power BI Community 

but I believe this is obsolete. 

How my modeling tab is shown: Can't access new column or new table buttons

Thanks, 

Ryan
