CEC problems any settings to try?

Since the April updates I am having a problem with CEC where my TV will keep switching over to the Vero 4K input when the Vero is not in use.
I am unsure whether this is a Vero issue or a problem with my LG TV as that also received a firmware update around the same time as the Vero updates.
Can anyone suggest some settings I might try to kill the issue rather than just turning off CEC please?

As much as I like the OSMC remote control it was quite handy being able to use my TV remote to control both devices, but at the moment I have had to turn off CEC to stop this annoying problem.

Disable set active source under Settings, Input, Peripherals, CEC
