Battery Questions/Concerns

I have a 2017 Leaf SL that I purchased pre-owned. it had around 8300 miles on it and was in like-new condition. I purchased it end of April 2018, it was manufactured in May 2017. It came from California. I live in the DFW Texas area.
A couple of days ago I noticed that it had dropped one bar on the battery bars. I currently have just over 18k miles on it. I drive 12.6 miles each way to work (side roads) and for errands around town. I rarely take it on the highway unless necessary (more because of traffic than anything else). I wasn't expecting to have it drop a bar this soon, with less than 20k miles on it. I know the climate here isn't the best (very hot summers) but it still surprised me. I have a co-worker that has a 2015 leaf SV (24kw battery) with just under 30k miles who purchased his also pre-owned a couple of months before I did. He has just a slightly longer commute than I do but other than we probably have similar driving use. He still has all 12 bars. Should I be concerned? I have read a little regarding the 30kw batteries degrading quicker than the 24kw. I have photos from the other morning of the bars and of LeafSpy, not sure where to upload them. LeafSpy shows the SOH of the battery as 83.94

If it doesn't drop another bar, that's not unusual. (Although the BMS my have been reset to falsely show 12 bars.) If you lose another bar any time soon, then that is cause to make them take the car back.

Read the section of my buying guide on the 30kwh leaf, if you haven't already.
