Generating Purchase Order

Generating Purchase Order

Under Vendor Tools on the Vendor Tab there is a "Generate PO for the Products below Reorder Level" option. When I select that option it takes me to a Select Venfor dialog with a drop down box listing vendors. The problem is that only one of my vendors should be showing on the list. Instead there are eight (8) other vendors none of whom are my vendors! They include the following names:
HD
Brazil Beans
Widget Supplier 200
and my faborite: Komurcuoglu Mermer A.S.

I don't know who these vendors are or where they came from. I looks like some Zoho internal test data. More interesting than that if I select Komurcuogu... a list of 10 products pops up, none of which I recognize.

What the "H" is going on?
