Fine metal shavings in oil pan

So last weekend I changed the oil for the second time in my 2015 grizz SE. I noticed that when the sun shined on the oil pan that there were very fine shiny shavings in the oil. I took a magnet to it and they appear to be aluminum. This appeared for the motor oil, and both diffs. This happened also when I changed the oils for the first time after the 200 mile break in. At that time the filter was heavy. On the second change it wasn’t nearly as heavy but still had the shavings in the oils. From what I read this appears normal on new machines. Can anyone put my mind at ease? Machine runs great!
First oil change: 200 miles
Second oil change: 638 miles
Filter seems much lighter on second change. I also put gold plug magnetic drain plugs on everything but this won’t take the aluminum out.
