Losing past data in analytics overview

Hi all,
I’ve noticed a strange behavior of the analytics overview. Some episodes start tracking normally, then lose their past data and only show the running total.

The data seems to be there, because the detail view of the episode tracks normally.

we are experiencing the same problem with our latest episode of Lila Podcast

any ideas what this is? or how to repair it?

thanx in advance

Background jobs are stalled somehow. Good news is: probably no data is lost (just not showing yet)

just wanted to note that it happened again.
