Community Admin@Memieee Will do, thank you for the video.
At the start of the video you're shown earning 126696XP. This would be enough XP to push your actual level up by 3. (1 nearly-finished level being completed, and 2 full levels of 54k XP earned)
However this is an impossible amount of XP to earn in a match, and it's actually showing cumulative XP from multiple games of Winter Express.
At 0:06 you can briefly see your actual XP earned, 9763. A respectable amount to be sure, but not necessarily enough to gain another BP level.
So while the summary screen is seeing inflated XP and giving "fake" levels, the actual progress is being correctly tracked, and you can see it on the Challenge page.
