When you view with the default sort you are viewing the order of items in the order you set them with the display order entry boxes. Models that have not yet been given a display order number (including new ones) seem to appear at the end of the Shop Inventory list when viewed in default mode, so you might check there, although I would expect long delays. Now I'm only working with default sort without any filters in Shop Inventory since at least that appears to be showing all models unlike other sorts or filters.
I have all sorts of problems with sorting and filtering but at this point I can't tell if it's just in my store or is happening for everyone. Since it's been about 36 days of problems since the upgrade I'm going to assume these things are messed up for everyone.
