There is an option byte in all the MDM7xx overlays which allows you to
"filter out" all control characters below Line Feed.  That's nice for
eliminating phone line noise-induced garbage, but plays havoc with
cursor addressing when using mainframe video-oriented text editors.
Turn the option off in your overlay and things will work right again.
