I cannot claim that 20 gems (10x2) when I complete Daily activities

Hello. For a too long time I cannot claim the 10 gems (20, because I bought Crazy Dave Premium Bundle) when I complete Daily Activities. I have completed once again today all Daily Activities, and when I pushed the button "Claim all", only that section with the 20 gems remains inactive, so I cannot benefit of that reward - screenshot as proof. Please, fix this annoying bug!
