duplicate proc

I have a proc listed in a database twice. I am unable to drop either of them. I think the problem started when I made a proc out of a function and maybe did not drop the function first. Someone had a similar problem last week, and was told not to delete it from sysprocedures. I did not see what the final resolution was. Does anyone know how to handle this situation? procname owner procid mode numargs isproc specificname -------------------- -------------------------------- ----------- ---- ----- ------ ------ ------------ makeinvwork informix 233 D 1 t makeinvwork informix 234 D 1 t sending to informix-list
