I kept clicking around the listing until the popover updated the item specifics but I couldn’t determine what finally made the item specifics update. I too did notice that “adding an attribute” addressed the problem but then I had to delete the extra “specific” back off, an extra step. Switching to live mode also works reliably as well as switching to “editor” mode. Both are an easier step than closing the popover and reopening it and dragging it to the side to be out of the way, either is an acceptable solution for the time being.
I am attaching screen shot of my working desk top. Two helpful suggestions if I may: Add “returns” by "SELLER/BUYER and the weight of the item to the listing so it can be easily seen at a glance.
OOPS… sometimes the weight is there and sometimes not. I will have to see why that is.
I found out why. Calculated makes it show up. It would be nice if it is always showing the weight. I have to enter the weight every time I ship something.
