Please be aware that you are only able to receive arena points for one arena team in a given week. If you complete the necessary requirements for your 2v2, 3v3, and 5v5 teams, you will be given arena points for the team which would earn you the most arena points.
Given that all three of your team ratings are below 1500 (which is when points start to scale with rating), and you have played the minimum games required for all teams, you will accrue points from your 5v5 team, which is 344.
