See attached screen capture - the bottom of the cumulative finds by month chart is a jumble of numbers. I don't see this elsewhere, so this may be an isolated bug.
Saw this using Windows 10, on Google Chrome Version 86.0.4240.75 (Official Build) (64-bit). Also spotted using Microsoft Edge Version 86.0.622.43 (Official build) (64-bit).
edit: despite no answer, the error has been resolved, so I'm closing the question.
