Titan bug: Colossal Capacity is invisible

In the last few hours I got my first ascendency chose Titan and specced in Strength and Colossal Capacity. The little Box Icon to toggle the Extra inventory on and off is there too but the Extra inventory isn't showing.

I tried to respecc these two points but that didn't work either. Then I got a few smaller jewellers orbs, tried to put them in my inventory but without me noticing they disappeared.
THEN I got one myself and tried to put that in my inventory as well and that one disappeared too but this time I noticed.
My theory is that the inventory is still there but I can't access it because it's invisible while the Box Icon doesn't work also and because the Extra inventory has Items in it I can't respecc it.

So does anyone have this Problem too? Maybe a solution? Because right now those are spent ascendency points I can't get back...

Help is very much appreciated🙏🏽
