Daily Messages Issues

[mehapps]

This is kind of a weird issue, my daily messages counter is currently stuck at 678, not sure where that number came from? Previously it was stuck at 1000 for all periods, but I think I left it on "past year" overnight and now it is stuck with 678. It was stuck at 1000 before (also not sure where that came from).
As I'm typing this I received/sent new messages, it moved up to 687 and I just watched it go back down to 686 lol.
I just did the calculation myself and divided total/days in a month and it should be around 1260. Attaching screenshots below of all 4 time periods
