Thread:Support/Statistics page: wrong sums?

I've not seen wrong sums for message groups in the statistics page for a long time, but just now.

If klicking "unfold" [opfallde] loads new datra dynamically at click time, the attached image may be a result of message editing between the statistics page was loaded an the "Wikimedia Mobile Apps" group unlfolded. Otherewise, something is wrong - see screenshot.
