Garmin Fenix 5x - Firmware 11.0 - Quarq Dzero - Power Meter - Issues.

I have the following issue and I would like to know if this is a hardware or firmware issue on my Garmin Fenix 5x. My Garmin stays connected to my Quarq Dzero Mtb Power meter, but it drops the Power, Cadence, and Power Balance data. I have attached a Garmin Edge 810 and the reading never drops on that head unit. I have also experienced quite a big difference between the two head units Power readings. I have attached a link to a zip file with all the fit files,

I am busy chatting with the support at Quarq as well, but it does not look like it something wrong with the power meter.

How do I get this resolved?

See my results are as follows;
