[2020] Implausibly High SPECIAL Stats

I have a Bloodied build with five mutations. Sometimes all SPECIAL stats will show at a level I could not achieve if I wanted to. Roughly they are about 10 more than normal. For example Strength was recently showing at 13. I have not invested any points in Strength, so its base level is one. Two Mutations drag it deep into negative territory, with gear and food etc raising it to low single digits. This miscalculation occurs both in a group and solo, with either Strange in Numbers or Lone Wanderer perks equipped. This problem has been occurring for months. [PS4]
