Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.1, 2.3.2-dev

Operating System (OS)

Windows

OS Version

10

Additional system information

No response

Printer

Ender 3 V3 SE Klipper

How to reproduce

Do a print that has multiple filament types.

Actual results

new_filament_temp and old_filament_temp values are swapped.

Besides custom GCODE implications, OrcaSlicer emits an M104 after every toolchange, even in SE/MM mode and manual filament changes mode. The correct temperatures are emitted by the M104s, but within the toolchange gcode template, it's as if the change perhaps has already happened?

Happens both in SE/MM and toolchange mode.

Expected results

The correct temp should be selected.
