DATESINPERIOD seems to be broken in the service

[ericleigh007]

The following formula works on the dekstop, but seems to fail in the service:

DATES_TEST = FILTER( OpenCharging, OpenCharging[Subperiod_Ending_Date] IN DATESINPERIOD( OpenCharging[Subperiod_Ending_Date], now(), -4, MONTH))

Substituting this instead gets things working again.

RecentCharging = FILTER ( OpenCharging, OpenCharging[Entry_Age] < 16 )

I added some measures to my dashboard to isolate the problem...  Hypothesis: The service is not properly filtering the DATES_TEST table, but the filter DOES work on my desktop.

Here's the service:

and the desktop

Notice that the DATES_ROW_COUNT is correct on the desktop, but that same table is blank on the service.

Hopefully others are seeing this problem and can confirm.
