Can’t display/purchase new items in latest update (Item limit error)

Just been checking and now it’s not letting me purchase any of the new items that came with the update. I have even tried removing the item I want to replace and  purchased another plot and started building another house to offload some of the items I have in storage!! I love the new items in the home catalogue - I just wish it would let me buy them and display them in my main house!! Any thoughts? Or anyone found the same problem?
