Certainly doesn’t help but will most likely not lead to refusal. You should be updating your marital status with CRA and you application will be amended. You can send in the amended NOA with you correct marital status.
Not sure how this is relevant. You could have attached NOA as proof that you support your spouse. Has nothing to do with applying inland or outland. You still need to fix your marital status because you may have received an incorrect amount of benefits.
