The charges a majority of Xbox One users are discovering with the usually free playable demos for FIFA 14 and EA Sports UFC are the result of an "error in the system," an EA Australia representative told Polygon, and should reset back to free within the next 24 hours.

Spotted by NeoGAF user WarpathDC, playable demo content for FIFA 14 on Xbox One was listed as $4.99. EA Sports UFC and FIFA 14 playable demo content was listed on Xbox One as $6.65 for Australian accounts when Polygon checked. EA Australia told Polygon that the error isn't on the PlayStation Network, but if it was, it's been rectified already.

The demo for EA Sports UFC launched for free on June 3 for PlayStation 4 and Xbox One and pits Jon Jones and Alexander Gustafsson against each other. The EA Canada-developed title was released June 17 on PS4 and Xbox One. Be sure to check out our review and our report on why Bruce Lee appears in the game.
