So the issue appears to actually be the Sales Order shipment Date.
What is being viewed in the Scheduler is Resource Type Sales Lines. Whenever I try and change the start date of the Sales line it automatically changes it back to Sales Order shipment date (which in the above post was the work date). Changing the shipment date on the sales order changed the default date for the Sales Line (for example Nov 22). But the bug still persists since any time I change the date for the Sales Line it defaults back to the Sales Order Shipment date. Is there a way to overcome this? Or am I stuck only being able to change the Resource type and not also the day itself?
