@Jean-Michel Anyway you can help with a resolution to this 5 year old issue?? Is there a way Shopify technical support can force delete an order?? The only "fix" proposed by support was to filter orders but this does not remove the notification for an unfulfilled order in the column on the left.
This is a solution I post here once in a while that has always worked for me, though some have not had success with it. Dean’s simplified procedure for getting “partially refunded” orders out of the “open orders” list (based on @Claire_Brennan ‘s):
this is terrible advice @Nicholas_O__Fe1 you guys need to redo your datatable structure.
how on earth does a cancelled order stay unfulfilled? it doesn't make any sense to the user. if you cannot fix the relationship within these two datasets, at least do a UI fix so we don't have to see the bubble count on the lefthand side. this is very poor UX and very poor data structure
