Guild War Defense team changed after team reorder

iPad Pro 11 in, iPad OS 13.1.3

I had set up all my defence teams last Monday, using team named GreenDEF for Day 6. Yesterday I created a new team for high level exploring and used the re-order option to move the team up to my other explore teams. Today I checked how my GW defense teams were doing and noticed that my Day6 defense team had changed to the team I created yesterday.
