We are currently using Manufacturing + Inventory on the online Odoo v15.

Background:

1.) We made 10 Manufacturing orders scheduled about 1 for every month.

2.) We have stock on hand and additional receipts of components coming in.

What I'm trying to achieve:

I just created an MO-011 that was supposed to be scheduled between MO-005 and MO-006.

I understand that the components were already reserved for MO-006, MO-007, MO-008, MO-009-, MO-010. So I clicked on 'unreserve' on each of the MO's after the MO-006 and on so that this new MO (MO-011) can use up the available components that would originally go to MO-006. 

The problem: The issue is that because I made the MO-011 later that the MO-006, it is at the bottom of the 'que' when I look at the 'forecast' of individual components. And when I click "Check availability" on this MO-011 it won't reserve components that are available for when the MO is scheduled for. It's as if since I made the other MO's earlier, they get to be ahead of the line.

Please help. Am I missing something?
