What you're seeing is normal. Channel is a host-side HBA parameter and with FC single port HBAs usually always 0. Target represent the storage controller on the storage array. If a certain partition on the LUN is referenced, an additional digit like vmhba0:C0:T1:L0:1 is added. Though I haven't seen such a notation in a long time, today esxcfg-scsidevs -m for example refers to a partition as naa.6000eb38a9ef4975000000000000082b:1.
In these views and generally, the runtime name omits partition information because it refers to the whole LUN as one block level storage device and not a single filesystem partition. It doesn't make sense to distinguish between partitions there or do multipathing based on partitions instead of a LUN.
