Hello @LaurentT1 ,

I copied your text, used a basic text program (such as Notepad) to completely strip its formatting, then pasted it into a fresh, newly added text block without any formatting. I then re-applied the formatting you had for your text, re-linked the email and website links, and deleted the old, problematic block. When previewing and testing the updated email and its new block, the erroneous text is not appearing for me. 

Please preview and/or test send your email now that I've updated it, to confirm you're no longer seeing the issue as well. Thank you!
