Your problem is you are placing effects on a model called "P10 Matrix" and then viewing them on the Christmas 2017 view where the matrix model is named "P10 Matrix-2". If you goto the Layout screen and change the drop-down to "All Models" you can easily see you have 3 matrix objects and "P10 Matrix" does not match the start channel of the other 2. So you are placing data at start channel 19325 and viewing it at start channel 11979.
