Looks like you may getting slices and partitions confused.  Generally your
partitions are subsets of slices eg:

ad0s1a
ad0s1b
ad0s1c
ad0s1d
ad0s1f

Where as your output is something like this:

ad0s1
ad0s2
ad0s3
ad0s4

Unless you have some pressing reason to do otherwise, choose the Auto
settings they are sufficient for most purposes.
