How do I update my store info? It is showing old info in the marketing emails

I have already gone into account settings and changed the name of our business a long time ago. For whatever reason it is still showing an old instagram account and old shop name/info at the bottom of the marketing emails.

There is no way to click on this section and edit the information in the email campaign editor.
Is there somewhere deep in Shopify where our store info has not been updated??

Hi, I have the exact same problem. @gallery_yi did you manage to solve this?
