The effects tab simply starts the applicable effects on the joystick. Unless "sticky" is enabled, a given effect that is configured on that tab will be overridden when a game sends a FFB command to start said effect.
Disabling an effect checkbox on the effects tab does not disable that effect type, it just doesnt start said effect from configurator. Only setting a gain value on the settings tab will effectively disable an effect type (such that a game can't start one with any strength)
In my experience, DCS does nothing except Spring and Periodic. If you set a damper/friction/inertia effect in the effects tab, it should persist.
UH-60 is a community mod that does not implement FFB.
DCS sets its own spring effect=0 during startup (overriding what you may have set in the effects tab, unless "sticky"). If a module does not restart the effect, the stick will remain limp.
