I noticed some issues in the German version for the PowerPoint Live Captions Menu. Below a screenshot, where the English version is compared to the German version.
There is an error regarding the translation of Bottom (Overlaid), which German should be Unten (überlagert) instead having 2 times the same translation. The second highlighted entry misses the word der, so that it should be Über der Folie.
The same problem is also present in presentation mode in the context menu, you can reach by right clicking somewhere in the presentation or on the three dots.
