Zed Explorer download calibration fails on ZED SDK 5.4

Software
1

When using the Zed Explorer CLI tool to download the calibration to EEPROM I get an error:

PS C:\Program Files (x86)\ZED SDK\tools> & '.\ZED Explorer.exe' --dc
*** Restore Factory Calibration ***

[ZED 2i 34489494]
Downloading factory calibration...
Writing factory calibration to EEPROM...
Calibration differs from factory settings (STEREO changed) ÔÇö updating...
Failed to update calibration for SN 34489494.

Details of the calibration as Zed Explorer sees them, and the calibration file itself are below. Does anyone know how to resolve this?

The values I can see in the Zed Explorer are like this (resolution is at HD720):

Hi @MathijsNL
What’s the version of the IMU firmware on your camera?
If it’s 777, please upgrade it to 778, retry, and let me know if the problem persists.

Firmware version is already at 778

I tested with another camera, which is running with firmware 777. Same issue.

PS C:\Program Files (x86)\ZED SDK\tools> & '.\ZED Explorer.exe' --dc
*** Restore Factory Calibration ***

[ZED 2i 32172731]
Downloading factory calibration...
Configuration file already exists... No changes applied.
Writing factory calibration to EEPROM...
Calibration differs from factory settings (LEFT RIGHT STEREO changed) ÔÇö updating...
Failed to update calibration for SN 32172731.

After updating this camera to 778 the issue remains.

Downgrading the SDK from 5.4 to 5.3.1 also gives the same error.

Can you try to delete the file SN32172731.conf from the C:\Program Files (x86)\ZED SDK\settings folder of your ZED SDK installation and let me know if this fixes the problem?
