Skyblock: Not able to move items in inventory

[svg3]

I'm not able to move items in my inventory in Skyblock. I'm able to click items but they're put back immediately to the original spot. In other technical words: It seems the InventoryClickEvent is cancelled server-side. Relogging or restarting the game doesn't work, nor does switching to another profile or lobby.
