date format difference in category view and article

In Menu Item Type - Magazine Layout I chose the date format d F Y. That is what is displayed in Category page (see screenshot). But in the article pages it shows date format only d F with Month abbreviation and day number. How can that be changed to a format like in category page?
E.g. category: https://fairer-urlaub.com/heizung/news
Content item example: https://fairer-urlaub.com/heizung/news/374-heizung-rechtzeitigvor-winter-pruefen

The article detailed page uses this date format: TPL_DATE_FORMAT_LC1

so I added a language override for this:

It's showing in d F Y format now.

Thank you very much!
