At least the German translation is broken: It has as of now 14 sections, the english one has 16; in German the English sections 7 and 8 are totally missing, the sections for Page weighting and Regular expression searches – and I know the are translated, because I was the one, who did the most of it. The Filters section in German has only 2 subsections, in English there are 7. (Edit: Oh, in fact parts of the Regular expressions section are present, but displayed as part of the Filters section.) So I assume somewhere in or after the second Filters subsection (Deepcategory) is a missing or misplaced <translate>
tag (or maybe vice versa somewhere before is one too much).
FWIW the translation has been broken with this edit: Special:Diff/2780543/2787288 on 21 May 2018, but before this the latest update for translation has been on 27 December 2017, hence some-when in this period the mistake(s) must have been occurred.
