So sorry, after recreating the file and re uploading, and when viewing again I was seeing the cached version. After clearing the cache its obvious recreating the file fixed it.
Also, I apologise for putting it into WDL rather than WD. I tried to edit my post to say this but had a lot of trouble as there appears to have been an issue with the site which has come right now.
Thats really weird after recreating the days, and the page correcting itself, I have this gremlin back again. Now it is showing the 27 day data when the 27 day hasnt finished yet
