Final Cut Pro title does not follow object tracker properly on a square project
I've started learning how to use the object tracker in FCP. I've been mostly having success, but it is not working when I'm trying to use it on a square project. I have 16:9 footage from my camera and imported it into a 1:1 project. The object tracker can find and track objects perfectly fine according to the tracker bounding box. However, when I bind a title to the tracker, it randomly wanders off and does not follow the tracker properly.
I feel like this has something to do with the fact I'm using 16:9 footage in a 1:1 project, but surely this is a common use case? (especially for instagram, etc.). The same behaviour happens with built in FCP titles or third party ones. Any help or suggestions would be appreciated. I've included a video of the issue and how I'm adding the tracker/title.
