Stats seem to work for 2008-march 2015, but as soon as I include all of april, the entire stats of april disappears from the details (but are still shown in the diagram above), this happens as soon as i include 1 april - 30 april, but not when 1 - 29 or 2-30 is included. It started happening 2 days ago and I was waiting for it to resolve itself, but it hasn't.
as you can see, stats just disappear as soon as the whole month is included.
overall stats are also affected by this and shows a total of everything but april (may is included)
thanks in advance
