In the Administration preferences chapter, under ReplytoDefault (https://koha-community.org/manual/latest/en/html/administrationpreferences.html#replytodefault) and ReturnpathDefault (https://koha-community.org/manual/latest/en/html/administrationpreferences.html#returnpathdefault) the internal references are not formatted correctly. "By default replies to notice emails will go to the `library email address <#libraries-groups>`__," The reference should have this format :ref:`library email address <libraries-label>` "By default bounced notices will go to the `library email address <#libraries-groups>`__," The reference should have this format :ref:`library email address <libraries-label>` I would also review those run-on sentences and cut them up.
