Help! Adobe Stock file will not let me change its font to font I desire to use for my actual logo

Hi there

I am trying to create a logo for my small business. I found a great design I liked off of Stock and imported it into Illustrator.

The font is set to EB Garamond ExtraBold, and it seems like I any time I try to move, edit, or create an outline to make it a shape, it automatically resets back to EB Garamond ExtraBold. I want to use Omnes Black Italic, which is a font I found on Stock and imported to Illustrator. It's wasn's saved in the regular list of fonts in the Fonts drop down menu, it's found in the "Find Other" Fonts menu. When I go and select the font with the Text tool and change it to Omnes Black Italic, the name does not show up in the Fonts name bar. Strange. My best guess is that because it's an imported font, it was automatically saved only on Creative Cloud (it has the little cloud next to it sans the download arrow), which may mean that it isn't "registered" or "verified" (for lack of better words)? 

Very frustrated, confused, and just want to turn my Omnes Black Italic logo into a shape so I can add a 3D effect to it so it can look more round!

Thanks in advance!

It's extremely frustrating!
