In my humble and respectful opinion, I do not believe there is anything you can do to get them to lay down flush without looking worse than they do now.

To me, the issue is that yellowish substance underneath the pinstripes where they are lifting. If I didn't know any better, I would think whoever applied those red pinstripes did not remove the paper backing before they were laid down!

See my above suggestion --> I would recommend gently peeling them off. Low heat and a bottle of soapy spray water should be all you need. Maybe a razor blade. Warm the stripes up where they are currently lifting, spritz them liberally getting the soapy water underneath the lifted edges, and gently peel them off. Including the backing paper.
For the pinstripes that may not yet be lifting, use a razor blade to lift a starting point that is inconspicuous. Then repeat as above.
