I file tax for 2021 BC. I am single, my income is less than $22,944, I tick CWB, but why the refund only increase by $10, as oppose $1,395? Is this turbotax error?

On CRA website it says, "The maximum basic amount is:
$1,395 for single individuals
The amount is gradually reduced if your adjusted net income is more than $22,944. No basic amount is paid if your adjusted net income is more than $32,244."
