重 here is read chóng ("again, repeat"), not zhòng ("heavy"). 重排 is the standard verb for rearranging items in order, retypesetting a publication, or reorganizing data — common in publishing, software, and scheduling contexts.
mistakes
Don't read 重 as zhòng here. The compound is 重 (again) + 排 (arrange) — "to arrange again". 重 always reads chóng when it means "again" or "repeat".
