Changing assigned vendor name

Client’s payroll is entered in bulk by journal entry, so those expenses do not have a vendor associated with them.

Somehow in Digits, all the je’s for payroll have become associated with a vendor name.  So that vendor name is consistently coming up as #1 in spend in the top 5 lists, etc.  I am guessing this MIGHT have been something that happened within assigning vendor names with the Boosts.

How do I:

1. Edit the vendor associated with these journals entries  AND/OR
2. Edit the vendor entry in digits so it can be called something else (ie: payroll)

Thanks!
