That's not surprising.  I don't believe Kodi supports adding or
editing anything in that area of MythTV.  Rather, it's probably left
for the user to configure sort of stuff in MythTV directly.

The database schema, protocol and services API are closely related and
a change in one area often ripples into the others but that doesn't
always have to be the case.
