Chain lightning issue

[Ulving]

Hi, I continued an old save where I started as an Elemental Rampager that chooses the electric rampage feat. It says that starting from level 11 that the lightning damage part is supposed to chain to 2 additional targets but its not doing it. I see the lightning effect on hit part, It shows the lightning damage roll on the combat log but its not damaging adjacent enemies....
I tried using rampage while in wild shape and without. I even though that maybe my old save is carrying some weird bug from 2 years ago, so i respect my entire build but it didnt work.
