Rhino 7 Title Block issues

I’m having a hard time with my Title Block Template. I created a new template recently and when I insert it into my layout, the Text Fields are from a previous version (not referenced in the new file as far as I know), and I can’t seem to update them. I thought I understood how this works but now I’m confused. Can someone guide me on exactly how text field blocks work? Is there a particular workflow for creating these in Rhino 7 for Mac?
