For the winter issues 17MMQ, 17MMR, 17MNP, 17MNQ, 17MNR : in 2021 there are only s1 data from january to may (checked also on PEPS) and regarding the cropcalendars the season finished in october that is why there is gapend issue.

emoved 29VNK, 29VPK and 30VUQ from the table because those tiles have been deleted from the production tiles list
