Strange date on download and forecast

I am still using WW .26…

I noticed now that there is a difference between the download date of the current weather and the forecast.
I mean today is the 14.5 and this is the downloaded date, is OK. But in the forecast for the next days there is still forecast for the 13.5, that was yesterday?! (see screenshot)

what is wrong?

Any difference with the following build?

with .28 it seems to be OK now, I installed it yesterday 15.5 and today the forecast begin with from tomorrow 17.5
