[Ticket Responded] Northelm missing an inventory slot on Xbox (Series X)

After upgrading Northelm to 35 (Legendary) I was looking to get a 4th extra slot for a total of 8. While I do see 8th slot on mobile, I do not see it on the Xbox.

Has anyone else noticed this and does anyone have a workaround (other than just sticking to mobile) ?

Something similar happened to me on Steam. The issue was that the vault window was too short for all the spaces, so I had to click and move it to the left for the last slot to appear.
