MDL-32585 it was detected that there are a number of _help (suffixed) strings in admin settings. Following the string documentation they should be _desc strings instead, irrespectively of their contents being the same. That allows separate editing.

2) perform the needed AMOS COPY commands to ensure all the new exist.
3) ensure this doesn't happen again (some check should be added somewhere).
