Removing System-readmore line from page

In the "System/Messages" section of Eshop, I toggled the "Readmore" button, which added a line to the top of the section, and saved it to see what it did. It added a line and pushed down the heading a little bit. I didn't want to keep it, but there seems now to be no way of removing it.

Please disregard this. I found out how to edit the code to remove the "System-readmore" line

That's fine Andrew!

Have a nice day!

Sincerely, Giang
