The original (en_US, C) “View” menu of the formula editor contains, inter alia, the items “Sidebar” and “Elements”. In the German L10N, *both* are translated as “Seitenleiste”, which is very confusing. Please use something like * “Sidebar” -> “Seitenleiste” * “Elements” -> “Elemente”
On pc Debian x86-64 with master sources updated today, I could reproduce this. Fixed in Weblate now: https://translations.documentfoundation.org/translate/libo_ui-master/officecfgregistrydataorgopenofficeofficeui/de/?q=note%3AB29Bo&sort_by=-priority%2Cposition&offset=1 Of course, now you must wait for synchronization + new version, etc.
