On the Item Database, a person has the option to sort weapons by type. I know that they are already sorted by "Type", but if you sort by "Name" and then click on "Type", the weapons will not be properly sorted. It appears the weapons are being sorted by platform and then by type when in that particular situation.

Here is an example:
