@myopkit2 not passing the buck mate - we don't have access to your game data, so are just trying to work out what we can from what we know.
That first screen, the one that shows the daily tasks, does not lock until you have selected your reward.
Per what i mentioned earlier, the Arctic Soldier reward section does not show a tick once you have selected the prize - it is clearly a visual bug though, because i did receive the mascherano that i selected and there have been no other reports so far that i know of.
Everything that you have shown in your screen shots is consistent with what is showing in my game, including the reward screen for Arctic Soldier.
The one screen shot you have not shown is the gathering rewards screen from the "main" tab in the heroes event - can you please also drop a screen shot of that section so that we can confirm that it is not picking up that the reward has been received.
I can then send on to the team and they can investigate further.
Thanks
