Missing font for a font I don't even use in my indesign document

[RashaTabb]

Hello.

I just opened my indesign file from another macbook and some of the texts have changed font to 'Roboto Medium' but with a '(TT)' on their own and now I have '397 missing fonts' in my preflight panel. I have already downloaded and activated all the fonts I use in my document and I have never even used 'Roboto' in the entire document. (see attached image). 

Some details: 

• I'm using Adobe indesign 2021
• I'm using macOS Mojave version 10.14.6
• I'm using the 'english + arabic supporting' version of indesign

I don't understand why this is happening. Any ideas? Some help would be highly appreciated. 

Thanks!

One more thing: 

I also tried to use command+f to 'find' and 'replace all' with the correct font but it gives me 0 search results for 'Roboto medium'... It's so frustrating.

Have you clicked on any of those page reference links to take you to the missing characters?

Are they Based on Styles?

If you have based any of the fonts on Basic Style - and changed the basic style etc.
