Ion V1.82. I have had the same issue since we got the board with 1.3.6. We have 24 ADJ P56P LEDs, 2 Punch Pro LEDs, and a bunch of the Par36 LEDs. If I use the correct fixture type in patch they will start to dim up and down on their own as soon as I select any color. I can set the colors correctly but they keep dimming up and down. I have looked at all the settings for the fixture and nothing seems to change it. The only way to get them to work semi-correctly is to set them all as an Elation Opti-RGB. Am I missing something? I brought in some Chauvet LEDSplash 200B fixtures and they seem to work fine.
