FTM Kinship Report Problem

[Patscga]

I have 5 cousins who are brothers and sisters, same parents. The genealogy
report shows them as such. However, when I run a kinship report, it shows them
as half brothers and sisters. I've done a check of their relationship to each
other and to their parents and it shows the correct information. So why is the
kinship report incorrect?
Thanks a lot.
