10% Chaos Resistance from Venom Drought

When I check my resistances, for chaos it shows (81%) on character selection it's over capped, yet when i check on poe2.ninja it shows 71% and undercap (havent checked pob because i dont use it), The missing 10% I am wondering if it's from the venom draught quest not being applied correctly or just a display error on poe2.ninja

anyone else experience this?
