My goodness, the more I think about the plot the more annoyed I am with it.

You're wrong it completely followed the rule

You only need oxygen mask when inverted (moving backwards in time). She (both of them) were moving forward in time on the boat.

What happened was she was shot and got inverted but they went back in time further than the boat trip.

Let's say, for simplicity, Day 0 was when she was on the boat, day 7 she got shot, they inverted, healed her up, gave her the inverted oxygen, etc. and spent more than a week going in back in time to before Day 0. They then unvertered (not really a word) so now there are two Kat's on Day 0 moving forward). One Kat is just a couple weeks older than the other from her perspective.

I don't quite follow the items, those are more of a headscratcher, but the people stuff followed the rules.
