Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2 Beta - Build cd5c8f2a

Operating System (OS)

Windows

OS Version

Windows 11

Additional system information

No response

Printer

Bambu Lab H2D (all nozzle sizes)

How to reproduce

How to reproduce:

Select any "Bambu Lab H2D" nozzle variant as the printer
Open any filament profile (either a system preset or a user copy of one)
Go to the "Setting Overrides" tab, retraction section
Try to tick or edit any retraction-related override checkbox (Retraction Length, Z Hop, Wipe, Deretraction Speed, etc.)

Actual results

Actual results:

Clicking an override checkbox does nothing. The label text highlights orange but the checkbox does not tick and the value field stays greyed out and un-editable.
If I work around this by switching to the X1C, ticking the checkbox there, saving, then switching back to H2D, that specific checkbox then works under H2D. All others remain broken.
If I then untick that working checkbox while the H2D is selected and save, only one of the two variant values in the saved JSON gets cleared. The other keeps its old value. On reopening the profile, the checkbox re-ticks itself but displays "N/A" because the UI is reading from the cleared index while the non-cleared index keeps the key alive.
The H2D Pro is not affected despite having an identical dual-extruder config. Only the H2D (model ID "O1D") triggers this behavior.

Expected results

Clicking an override checkbox should tick it, populate the value field with the machine default, and allow me to edit the value, the same way it works when the X1C or H2D Pro is selected.
Unticking an override checkbox should fully clear the setting for all variant indices and revert to the machine default.
The Standard Flow / High Flow nozzle variant selector (present in Bambu Studio for H2D-class machines) should ideally be available so the two-element variant arrays can be edited properly.
