I noticed in version 7.1.12 that when choosing a range of channels including channels that are not being used and then selecting "Set Value of Selected Channels on All Steps" results in those empty channels being set to a value of 2 or 0. This was an old error. This should not result in an unused channel being set to any value. It should continue to be blank. This was a problem years ago, but has been corrected for at least the last 5 years.
Thank you for your help.
