"Win X Rounds" Challenge

[Elite1111111111]

The challenge description says to "Win X Rounds" (I believe the lowest is 10) but it is for winning whole games. This means either the achievement description is wrong or the unlock condition is wrong.
Reached Gen 8 and figured I'd play Last Titan Standing since it's at least 4 rounds and was dissapointed when I realized it was for winning games. So I feel the description should at least be changed to "Win X Games"
