Security feature disappears and/or throws error after initial creation/upload

Roles in the Security tab are working fine for me to.  This issue occurs when I try to modify or return to the security tab after the initial publish.  

I've included some screenshots

I am able to successfully enter my role membership after the initial publish.  However, when I return to the dataset (as pictured below) the word security has disappeared from the menu.  

Typically, refreshing the browser window will bring the Security option back.   

However, when I try to access the security tab at this point, it generates an error.  This dataset will continue to throw this error despite all my efforts to overwrite it or refresh it.  The only solution I've found is to completely delete it, and republish.   Importantly, the roles and report still work, I am just not able to modify or access the security settings any more.  

This tends to happen with my larger datasets, but as I said, it's not happening to all of them.  Strange behavior, and I welcome any advice or suggestions you might have.  I have also opened a ticket with the Power BI regarding the same issue.
