I am trying to bring in a game from a web database but the default team and 1 player's mapping is incorrect. How do I override it when it shows a check mark.

Once you have mapped a team, it can not be undone. If we allowed unmapping and re-mapping, it would allow people to create "circular references" and create the same player/team mapping to multiple teams on a device.. it would be a real mess.

You can use Merge to combine a team or player with another team or player after importing, but you can not undo the mappings.

I don't think I actually got to the place I approved the mapping.

If you were never given the option to map then the person you are sharing the data from either already mapped or had the same players as you on their device.
