Mistake in Vault.ObjectOperations.GetCollectionMembers function?

Hi. I am solving some problem with "automatic" export of members of document collections and during my work I probably found some mistake in this function.

I can get ObjectVersions of all members and (for some reason) need to check if then member is in "Latest version" or "Specific version". For this there are two ways -  ObjectVersion.ObjVer.IsSpecific/IsLatest function and ObjectVersion.ObjVer.VersionEx.Type (values MFObjVerVersionTypeSpecific/MFObjVerVersionTypeLatest). Both ways returns in my case the same and wrong information - SPECIFICVERSION. I can see in dialog for Document collection Members that one of them is Specific and second is Latest, but via API functions  there are only Specific...

Thx, JJ
