Hi,
I discovered that if a page have more than one group in the info table it's only the last group that is shown,
Like on this page: https://en.m.wikipedia.org/wiki/Kliment_Voroshilov_tank
Version: WikipediaApp/6.9.3.1980 (iOS 16.0; Phone)
Testing steps for QA
Go to article Kliment Voroshilov tank on EN Wikipedia. Confirm you see all the tank infoboxes, like on Desktop, instead of just one.
