novation launchpad LPX erases controller settings when LPX starts up

I read some where that this is a bug in the latest LPX version.

You set up a Novation Launchpad (mini MK3) in controller settings for 90 deg rotation and as soon as you exit LPX that change is gone.

If there is no fix for this is there a way to fall back to a version of LPX that works ?

Thanks in advance for any help
