This is directly from the manual, schedules are not the same each season if you are using the Standard game start, there are multiple schedules included so the interleague games are switched up each season.

If only one schedule matching the league configuration exists, then in subsequent seasons the same schedule will be used, but the precise team matchups will be randomized. In other words, the pattern of games will be identical, but the matchups will be different from season to season. If more than one schedule matching the league configuration exists, then OOTP will cycle through the schedules.

If OOTP finds more than one matching schedule for a given league configuration, it can "link" those schedules and use them across multiple seasons, allowing the user precise control over their schedule year-to-year. When multiple valid schedules exist, OOTP chooses a schedule by reading the values contained in the "comment block" of the schedule file name in alphabetical order. For example, let's say you have created 3 schedules that all match a league you have created. The league has 162 games, interleague play, an unbalanced schedule, and 2 subleagues with 1 division and 8 teams each. You have named your three schedule files as follows:

ILY_BGN_G162_SL1_D1_T8_SL2_D1_T8_c_a.ldsl
ILY_BGN_G162_SL1_D1_T8_SL2_D1_T8_c_b.ldsl
ILY_BGN_G162_SL1_D1_T8_SL2_D1_T8_c_c.ldsl

OOTP will recognize that all three of these files match the league structure, and in Season 1, it will pick the matching schedule with the highest alphabetical value in the comment block - in this case, the first file, because the comment block is "a". In Season 2, it will remember that it already used "a" last season, and will use the file ending in "b". In Season 3, it will use the file ending in "c". Then, in Season 4, it will cycle back to "a" again, and the cycle repeats.
