[Bug]: settings on screen keyboard

[Rivarossi]

Version of OpenTTD

12.2 - win 7

Expected result

read in the settings window the options of the setting "on screen keyboard" (disabled, double, single, immediately)

Actual result

The setting works in game but in the settings window, even when changing the option, it is always shown disabled (see screenshot https://ibb.co/8XZGkFm )

Steps to reproduce

1. open the settings window in game
2. click on interface
3. click on general
4. click on the arrows of the setting on screen keyboard, the setting changes (checked in openttdcfg) but it always reads disabled
