An error has been reported where Xero Invoice Option in Wise-Sync is set to Detailed.

NOTE: This article only applies if you have the Invoice Option set to "Detailed" so that invoices created in Xero will include the detailed time entry information.

ConnectWise have noted this as a result of the "Detailed" option being removed from versions 2014.5 and 2014.5. It is expected that this feature will return in v2015.1 > CW Ticket > #4614943
