Missing a day in moisture balance detail

I was looking at zone moisture charts on the android app but when I filled down to the detailed moisture balance table I found that a day was missing:



In this case yesterday, the 18th. Is this a known bug?

@WokingWounded do you mind posting the link to your PWS here? I would like to review that data.

If one compares the android app and the browser version it becomes clear that no day is ‘missing’; the data displayed is for the same 6 consecutive days (14 to 19 inclusive) but the android app labels them 13 to 19 with 18 omitted. My pws is at:
