Visual Editor not showing up

Hello- I have Vantage and have Black Studio TinyMCE Widget installed- website is bioflagtherapeutics.com. I am not able to see any “Visual Editor” (formatting options), such as centering text in a box, etc.
when I first open the page, I do see a Visual and Text tab briefly, but then the editing area is filled with my columns and modules- the only options I have then are “Live Editor” and a text sentence “Revert to Editor”, which isn’t even in a box and is overlapping the “Live Editor” button in a confusing manner. When I click “Live Editor” I see the same rows/columns with the website itself on the right side- but no formatting options for text fonts, centering, etc.
When I click on “Revert to Editor” I get the warning box: “Would you like to clear you Page Builder content and revert to using the standard visual editor?” When I did this, I lost all my content and good thing I had the page backed up elsewhere.
I have deactivated all non-Site Origin plugins and then cleared the cache- still no Visual Editor where I can format text and image placements, etc.
I check other threads with a similar problem but they had a non SO theme- again, I’m using Vantage.
Any help would be greatly appreciated.
