Hi @Stan Vigurs
Were you raising fixture 14's channel fader, and noticing that it was also adjusting fixture 26's intensity? If so, I would recommend testing your console's faders.
To do this, switch off the console, and then switch it on with the SETUP key held down. After around half a minute, the console will boot into Test Mode, with a virtual front panel shown on the internal touchscreen. Please move each fader up and down, and check that the console is registering the level of the faders correctly. If a physical fader's level does not match the fader level the console is registering onscreen, or a physical fader activates a different fader onscreen, please let me know, and I can advise the best steps to take.
To exit Test Mode, switch the console off and back on again, and it will then boot normally.
Please let us know if you have any questions.
