I solved my own problem!

"Find_and_DeleteBid" triggers another auto macro, so now my code looks like this:

Case Else
 Application.EnableEvents = False 'this disable any macro that is trigger any other auto-macro
                    Run "Find_and_deleteBid", Target.Offset(0, -3) 'check if job exist in orders selected. if so, deletes it
                      Target = ""
                    Application.EnableEvents = True
                End Select
