Understand how prelam and postlam core boards lock finish sides
Learn how a core board SKU's lamination type decides which panel finishes you can edit and which are bundled from the catalog.
A core board SKU carries a lamination type: postlam (default - both finishes editable/inherited), prelam both sides, prelam external only, or prelam internal only.
On a prelam side the finish comes bundled with the board: it is taken from the finish SKUs linked to the core SKU in the catalog.

When a core material carries linked finishes, those finishes are applied automatically to the panel and the finish field for that side is locked, so the designer cannot change it there until the core is switched back to a non-prelam board.

If the same board is used as a shutter it is treated as a shutter board rather than a one-side prelam, which changes how the board layout is calculated.
Changing the core material regenerates the panel's board layout, because the core SKU determines the board type and thickness and the panel geometry is rebuilt from it.
A cabinet modelled at one panel thickness can be switched to a different thickness by changing the core material assigned to it, without rebuilding the design at the new thickness.
For a panel whose internal side is pre-laminated, the internal and external finishes cannot be swapped directly.
To get the desired finish, create a prelam external board in admin.
To get the desired finish, turn off the existing panel and add a custom panel that can be rotated as needed.
