I have recently updated out console to 6.0.4.
I have tried using [Update] & [Master button] to update the contents of a preset on a master. The preset gets updated with the selected channels, but the master retains the channels & levels from the previous setting. The master is usually up, but fading to 0 and back does not update.
Fading to 0% and using [Page+] [Page-] refreshes the master and it gets the correct preset content.
On 5.1 I used to use [Record] & [Master button] which brought up an update dialogue if there was already a preset assigned which updated the master correctly - but 6.0.4 doesn't give that option.
