CEM beds and chests are not shown correct in the inventory

[Norzeteus]

In my ressourcepack I have made cem custom beds and cem custom chests. When you place it, they will work correct! The only problem is, that in inventory there are shown the "normal" MC beds and chests. Im knowing about the ne "items" folder but I cant figure out how to get my entities there...
