In No Split Mode, there is an issue.
Deleting orders cannot be done from the dialog box above. Has to be done from the "orders" list, below.
In large maps, finding the order in a big list is hard. I am playing 62nd move of big map no-split game and it's old now. Sometimes, must clear all orders just to correct one.
Please add a "delete" button to the above dialog box.
Alternatively, if you click the territory, the orders in the "list" should "filter" based on selected territory.
PS. I cannot find the "feature request" page, I can cross post this there.
