I am working on an assembly that was created by a coworker and the BOM is showing 5 components when the assembly only has 4. I first thought that maybe it happened to have been patterned one extra time but that is not the case. I went into my assembly and deleted all of the problem components and checked my design tree to make sure I had none of them left, yet the BOM on my drawing says I have 1 left. Any thoughts???
