Unable to save core settings using dual sense

[GeoNeo]

I just got a mister and I'm unable to save settings per core even if I press any button on the DualSense controller.

When you save core settings should a prompt come up on screen confirming the save?

Any help would be appreciated.

No prompt comes up after clicking on Save Settings.

no prompt. just save.
if you want to check go via FTP into your SD card and check the config forder
