This is only happening today with one particular order. When I go into the order and select to fulfill order... I make sure items are checked. I fill out tracking number and hit fulfill. Message confirms that i have fulfilled my order, however the 'fulfill items' button at top stays black (i.e. doesn't turn grey) and no little truck/shipping images appear. Back to order page and it shows the order as not being fulfilled. Have fulfilled other orders without problem. I have refreshed screen. Logged in and out. Tried it a bunch of times. What is going on?
