OK, then the settings are being applied but there is something in your system that is lowering the GPIO 26.
Do you have any sensor, device, HAT connected that could be trying to use the GPIO26?
Do you have any setting or program that could be trying to access to the GPIO 26? openplotter-gpio app, openplotter-notifications app, node-red, any python script...?
Performing a fresh installation of OpenPlotter v3 may help rule out configuration issues.
