Try using at in the range of 0.7-1.0, I'm not sure what happens if u go beyond this cause I'm new.
I personally did 0.9, while making sure my other loras are at 0.7 or lower to 0.5.
(psst, also, model doesn't change to NoobAI-XL (NAI-XL) when u click "use lora" for some reason... or could just be me..? Whatever, not like you have to use it!)
