Repeated elements in translations of a block view
You have to add a filter:

FILTER CRITERIA

Taxonomy Term: Translation language (= Content language selected for page)


or if the content language is not available when configuring the filter:

Taxonomy Term: Translation language (= Interface text language selected for page)


Otherwise you get a row for each translation, which are then all rendered in the same language, the one of the page, because you have configured this in the section Language in the middle column of the View.
