Brightness doesn't seem to work through multi-sync

[Taylor-Tyson]

I am having an issue where I have a kulp controller and a Pi that both have the brightness plugin. The pi is set as the player and the kulp is set as remote.

On the brightness configuration page, it states: If FPP is running in Player mode with Multisync enabled, changes to the FPP device's brightness will also be sent to all the remotes that also have the Brightness plugin installed.

Whenever I adjust the brightness on either the player or remote, the brightness will continually go up and down. This causes the lights to flicker. Is there something I am missing or is this an issue?
