Don't forget the Underdog points require picking the winner who PLAYED AS AN UNDERDOG.
In your first example, it appears that player had predicted Xavier to beat FGCU. I'm basing that on what appears to be a red (incorrect) entry for the first round FSU vs. FGCU matchup. Picking an 11 seed (Xavier) to beat a 14 seed (FGCU) is NOT an underdog pick. Therefore, no underdog points would be rewarded.
The second example picked Xavier (11 seed) to beat FSU (3 seed). Xavier played as an underdog, therefore the underdog points were awarded.
This has been the requirement for YEARS. From the help file in TT:
IMPORTANT NOTE: To get points for Underdog Scoring a player MUST correctly pick a team to win a game as an underdog AND that team must win the game as an underdog.
