(2) as discussed with zalex, string change that only changed  to "" should also be reflected in all translations that had those strings translated. it should be made so that these translations are not lost (both msgid and msgstr must be properly changed). it should not be changed for languages that didn't have those strings translated.
if in doubt, consult translation maintainers : https://zabbix.org/wiki/Translating_Zabbix
<pavels> But he didn't change only of those strings. Or am I missing something?
