Actually, all of those answers were part of treaty agreements between the United States and Great Britain in 1817-1818.
The one that seems odd in the list is "Oregon Country disputed," because that was a matter not settled at that time. In the Treaty of 1818, the two sides agreed to some joint occupancy of the Oregon Country for ten years. Actual resolution of disputes over joint occupancy didn't come until the Oregon Treaty of 1846.
