Mass issue to MFG

Hi

We have run into an issue, where Mass issue to mfg will sometimes more often that not. Be issuing more parts than requested.
We have had examples, where it there has been mass issued 2x up to 5x times as many parts than needed.

We have look into the data directive, method directive for any BPMs, we have checked latency, all parts setup. But we have been unsuccessful so far in locating the issue.

Does anyone have similar issues or fixes?
