Pan envelopes display setting not being saved.

Hi guys
Can someone please verify this behaviour.

Go to preferences (press p) and then go to the "Display" section and deselect "Display Left on Top for MIDI Pan Envelopes" as I prefer left on bottom (to match Pan controllers in PRV view). Then hit OK

Then go back to preferences and check the above setting again. On my system is reverts to selected every time.

I am on Sonar Platinum version 21.01.00 build 38 and my Windows 7 32bit is fully patched as on Today

regards
Paul
