7th anniversary equipment on main character disappeared

why has all of my 7th anniversary equipment on my main disappeared? On the heroes it shows. Roll the mouse over the equipment it shows the gems and advancements. I double clicked the empty icon for the boots and put a low level boots on. It shows up, I cannot see the 7th anniversary equipment in the inventory to put it back. This unit was maxed out a lot of things. If GT has disabled my equipment on my main character for some stupid reason. That's the good excuse to quit that will take years to replace
