Why am I not seeing spot reports in gridtracker2?

I built the PotaPerformer in the standard configuration with the feed point about 4' high and 2, 16.5' elevated radials. It works great. The other day I watched a YouTuber add 2 more elevated radials. They were positioned in different directions and he said it worked really well. So today I added 2 radials to my PotaPerformer and located the 4 radials 90° apart. My IC 7300 tuned it ok, but my analyzer showed an almost 4:1 swr on the 20m band. The swr was actually much better on the 17m band. It suggests to me that my 17' whip is too short for 20m using the additional 2 radials. I guess I shouldn't complain, it worked, but not as I expected. Thoughts?

I put up a doublet cut for 10m down to 20m. The emergency tuner on the 7300 will "tune" all of those bands, but I lose 50% of my power. So, I purchased the Antuner AT-100m to be used with my doublet. It allows me to transmit at 100w. My question is, for those using that tuner, what are your configuration settings? I am curious how others have configured it.
