Question about using Harmony Ultimate for Tivo

I have the Harmony Ultimate programmed for my Tivo. For the most part, it works well. But, when I switch over to Roku, it puts my Tivo on standby. I am using the activity feature. When I click to use Tivo, it turns TV on and changes the input. When I click to use Roku, it changes the TV inut by send the Tivo into standby, which stops my recordings. How do I set it so it won't send my Tivo to standby?

Anybody else using the Harmony Ultimate? How do you like it? How are you set up?

Thanks
