Di server / B1ws Enum issue

I have an issue whereby if I set a row in a picklist as picked via the UI and then try to retrieve that document via B1ws I get the following error

Invalid valid value 'Y' in Enum 'BoPickStatus', the valid values are 'R', 'P', 'T', 'D', 'C'

To recreate this .. open a picklist in the UI and then set a rows pick status to picked. The open that pick list in B1ws using the getbyparam .. if you are like me you should get the same error.

This does not happen if I do the whole thing from b1ws but if I pick some from ui and then some from B1ws I get this error.

I found another post pointing out a similar issue, but it does not appear that issue was ever resolved. >http://scn.sap.com/thread/3266489

Any help would be appreciated.
