Nroeberg welcome to the QR forum. By the end of this year you should be able to find answers to this sort of problem on the dashboard. There are many questions you can already find answers to already.
I do not think it is usual that two different upgrade offers are made for a single flight. A possible exception was noted several months ago. I would not count on their being a second offer.
Have you investigated the cost of purchasing an upgrade for that sector yourself?
