This has nothing to do with alignment; it is because your first and second extended partitions have no space between them to hold the EBR. This space has been required by parted always and in the past all other partitioning tools were believed to honor this requirement, but for some unknown reason, a few people every now and then somehow find another partititiong tool that lays out their table this way and parted won't accept it.
