I have been looking into this today myself, being new to bitcoin. I use Exodus wallet and discovered that you can decide (pretty much) what to pay as a fee by moving a slider left and right. The less you pay the longer the transaction takes to complete, of which is fine by me.
Can't enlighten you on the weirdness as I don't get it myself but you can bring the fees down. I also had to cancel a few orders for the same reasons as you and as far as I am aware, as long as the order is cancelled, its fine.
