D&Y Painting Stand vanishes after packing from Build Mode

[MakuDesu]

I'm not sure if this is another bug, but I bought a D&Y Painting Stand in D&Y Store, waited for a few days, I made sure I had available slots in my inventory, I accidentally packed it but It didn't go to my inventory, instead it just vanished, unlike other items that went straight to my inventory after packing it

Looking into it! Sorry about this :(
