External settings don't work. FW arducopter v 4.0.0 Matek F405CTR

Please help me understand why the settings in the picture are not active

RC6_OPT, RC7_OPT and RC8_OPT have been deprecated. There are a lot of posts in this forum about this. Please use the “full parameter tree” on the left menu.
The documentation is here: https://ardupilot.org/copter/docs/parameters-Copter-beta-V4.0.1-rc2.html#rc7-option-rc-input-option

And please update to 4.0.1-rc2 ASAP.
