Translation doesn’t work properly

I am having some issues with the translation of the plugin into german. Some elements are still shown in English, although I translated them with “loco translate” to german.

“Loco translate” Page (label “Last Attempted”): https://ibb.co/12mr7DC

In the example above, please have a look at “Last Attempted”, which I translated with Loco translate however it stays in English, and “Next” for example works or the red highlighted text “Fehlgeschlagen”. I am really confused why some elements work and some not. Also translation for the table below “Last Attempted” doesn’t work.

Any help is welcome.
