"Group X Bugs Access" drop-down menu item

[Joseph Phillips]

I have a bugzilla 2.10 installation.  This has 4 products.  When the
user goes to enter a new bug on any of these products, towards the
bottom of the page there are 2 drop-down menu items.  The first one has
two choices:

1.  "People not in the 'Group 1 Bugs Access' group can see this bug"
2.  "Only people in the 'Group 1 Bugs Access' group can see this bug"

The second drop-down menu item has the same two choices, but for 'Group
2' instead.

I do not have "usebuggroups" or "usebuggroupsentry" turned on (and I
never have in the past).  So why are these menu items appearing in
bugzilla?  I don't want them to.  Thanks.
