It can also be caused by excessive regens, but that does not seem to be a problem being reported on this site.
I've been doing UOA for 9 years and had one similar to that when I was doing quite a bit of short distance (< 5 miles) city driving in winter. This was on a CRD Jeep without a DPF or regens. In my case, the engine oil never really warmed up enough to evaporate the fuel that gets past the rings when the engine is cold.
IMO, nothing to be concerned about, unless your driving was all high speed, long distance, high temperature driving on that UOA interval.
That silicon reading at 36 is a bit high. You may want to check your air filter to see if it's seated properly and the clamp on the airhose connected to the airbox is not loose.
