Employer Job Offer: International Student stream OINP Issue

[Indiana jones]

I recently got ITA for International student stream (OINP) few weeks back. I submitted all the documents already. I checked my EOl results it showed two Canadian credentials and I got points for it 10points which is incorrect I just have one Canadian credential (5points) upon further inquiry from OINP I got to know that I added same education info twice which is why I got points. Although even if 5points are taken off I am well over the cutoff wanted to know what should I do in this case? Should I withdraw the application it's still in submitted status or should I send a support letter highlighting the issue? Please help
