I don't think this is a bug.  You've got values that didn't make it into
the MCV list, but nonetheless occupy multiple buckets' worth of space in
the remainder of the distribution.  They *should* appear multiple times
in the histogram.  If they didn't, the histogram would be understating
their frequency.
