Bug... Inventory full on 2nd hero

I purchaded my 2nd hero slot today, hired my main, and got new hero to level 5.
Then I can’t pick up items because I get the inventory full message, even though nothing at all in my two bags. Please help as this is frustrating and a waste of my purchase.

Dont worry… solved. The first hero’ s inventory was full. I did not realise I could access both hero’s inventories. Thanks, this is actually quite helpful.
