Pop-up dictionary changed?

Has the source of the pop-up dictionary changed recently?

When you pause the video (Netflix) and hover the mouse over the target language, a pop-up dictionary conveniently shows the translation in my native language.

I’ve noticed that the translation is not as standard as it used to be, as if it were crowd-sourced. Also shows up in two lines (of irrelevant translation).

What’s changed? i have not tweaked any settings in my profile.

I tried to keyword search any relevant note, was not able to come across any info.
