Certain gschemas.override arguments are not being applied

I used dconf watch / to make sure I've applied the correct settings, however the following settings are not being applied at all.

[org.gnome.mutter]
dynamic-workspaces=false

[org.gnome.desktop.wm.preferences]
num-workspaces=3

[org.gnome.shell.extensions.dash-to-panel]
panel-element-positions='{"DEL-CXXXXX3":[{"element":"leftBox","visible":true,"position":"stackedTL"},{"element":"showAppsButton","visible":false,"position":"stackedTL"},{"element":"taskbar","visible":true,"position":"stackedTL"},{"element":"centerBox","visible":true,"position":"centerMonitor"},{"element":"rightBox","visible":true,"position":"stackedBR"},{"element":"activitiesButton","visible":true,"position":"stackedBR"},{"element":"dateMenu","visible":true,"position":"stackedBR"},{"element":"systemMenu","visible":true,"position":"stackedBR"},{"element":"desktopButton","visible":true,"position":"stackedBR"}]}'

For Dash to Panel, the entire string is one argument and was copied and pasted from a fully configured system. Pasting this same argument exactly into the terminal works no problem. Is it possible the settings are being overwritten at some point during installation? If so, is there a script I can run to apply these before the first-run?

edit: dash-to-panel uses unique monitor identifiers for some settings, which then fails to apply the settings on other computers. I will close this since it's unrelated to Blue Build.
