Switch, Witch doctor set bonuses LOTs of bugs

I have a witch doctor on the switch that is having issues with multiple sets not giving bonuses. I am not getting any sort of defensive bonus from arach set or the Helltooth set…I double check that the bonus is even highlighted on the gear and not greyed out, but I don’t get a buff from either, neither is it shown in the stat sheet for any kind of damage reduction or life percentage from the one set. Like I said I double checked multiple times that the set bonus was highlighted and should be active. I am new ish to the game but I have two other max level at 100+ gr so I mean I get how the game works in general to know I should have a bonus active and how to check if it is or not.
