Lights stay lit

[gemoomaw@gmail.com]

2 problems

I have one controller (#10)      (fpp + falcon Picap). When I activate string O it lights the registered number of lights. When I activate string 1, the first 1/2 of first string on 0 stays on.  This 1/2 string stays on no matter what I call for. I can only turn this off is by powering down.
I have swapped strings but always the first 1/2 string stays  on.
Ideas?
Problem 2.
The other controller (17) acts normally. If I try to use only (17) it will disappear if left powered on for a period of time. It will reconnect when powered off then on but that is not the way I want to use it. I want to leave the controllers powered on continually and be able to find them when returning.

For problem #1, post your config. It sounds like overlapping channels.

For problem #2, is that also a falcon picap? Which rpi is attached? What version of FPP is loaded?
