Maryland non resident refund denied... HELP!!!

I have a client returns from 2024 and 2025 which the state of Maryland is refusing to issue the refund and it appears to be with how the software is handling the non-resident income. The Customer is a VA resident but had one W2 from MD. State of VA taxes all the income hence I filed a non-resident return for MD. Apparently it had to be a paper return because when I check the box which says not required to file, It doesn’t let me e-file however the refund is denied saying there is no MD income on the filed MD return. Looks like checking that box zeros out MD income making it possible for a full refund to be issued for taxes withheld. 

I need to file an amendment to get the customer’s refund- I’ve done it before and didn’t get good results hence I believe I’m not doing something right. ProConnect support hasn’t been helpful either. Has anyone been through this or have any idea on how I can effectively file this to get the customer’s refund approved?
