I never have had condensation in my Tremor but other vehicles I have owned have done that from time to time. It usually occurs under the right atmospheric conditions and washing/rain on your vehicle. As long as the water is not puddling in the lens then it will go away on its own. I would not be concerned, I also get it; it would bother me also.
The first day of ownership I had the same thing in both. Haven't had it again until last weekend. My 2018 expedition gets moisture in every single light, Ford replaced most of them and they still have moisture in the all the time.
