How to delete a hyperlink

[IMAZTriBabe]

I downloaded the 2024 SoftMaker NX for Windows, 64bit, a few days ago. It Installed just fine. When I update content on an existing PlanMaker document, when adding my email address, it creates a hyperlink. When I go to the tool bar, under Contents, the option for "remove hyperlink" is grayed out. i do not have access to that option. How can I make that option, selectable?

Thank you in advance...
