System.Object[] Directory Sync

In our directory sync, which is syncing to an active directory…in the even there is a multi-value in the field - for example - a phone number contains TWO phone numbers in active directory…the sync returns “System.Object[]”…which from a .NET perspective I know why this is happening…but is this a bug that can be fixed or is there something I can do (outside of removing the extra value?)

Thanks!
