OFFICIAL Storage on the farm

[BethFB]

In the game on Facebook, I have around 30k in Copper and around 56k in Iron Ore, but when I switch over to the game on Slashkey, I have zero Copper and Iron Ore.
So is the game on slashkey behind the times or is it a glitch as I would refresh the game on slashkey, I would check it to find that I have all of my Copper and Iron Ore in my storage and then a few minutes to a few hours later, all of it is gone again.
Is it a glitch on slashkey?

Thanks.
