I can't figure this out.  The spoilers extend automatically when I advance the throttle.  It doesn't matter if I have auto throttle armed or not, or RTO armed or not.  When I advance the throttle fully the spoilers retract but then constantly want to deploy but immediately stow again.  Any ideas?  This just started recently.  It started before updating P3Dv4.1 to 4.2.  It happened in version 4.2 and I completely removed P3D and reverted to version 4.1, it still happens.  I removed all of the spoiler, reverse thrust commands from my controllers to keep the commands strictly to the keyboard with no result.

Thanks!

After updating versions, it is a good idea to re-assign and calibrate all axis.
