Duplicate name PBU-1123-0001 already exists

i found a Duplicate name for sales invoice PBU-1123-0001
sales invoice PBU-1123-0001 already exists

This is because the naming series may not have been updated with the very latest new task number. But when I try to use a naming series for Tasks and starting at 67, it still didnt work.

Any ideas?


Please update the naming series for Sales Invoice.
