Controlling timeline using Unity Playable Controller not working properly

Hello, 
Yes I have unchecked the Play on Awake. I tried with different wrap modes as well, but that doesn't seem to be it. 

My timeline only contains activation and animation tracks, if that is of any use, and everything works as it should when I manually pause the timeline in the Unity editor during play mode. I have also done a simple test scene with a very simple animation and timeline, in case there was something with the timeline in my main project, but the same thing happened there. The issue only happens when I control the timeline via the control panel in Mesh. 

Thanks for your help
