Part-time fee more than the maximum chargable fee

Hello,
I completed an undergraduate degree many years ago, but have since changed career path. I have been offered a place to study Biomedical Science (BSc) as a part-time student at the University of Bedfordshire over 6 years, starting in October this year. As far as I am aware, I would be eligible to apply for student finance despite my previous degree, as my new course is part-time and classed as an ELQ exemption.

The applications for part-time funding opened on Monday, but I am having difficulty completing the online form as I am getting an error when inputting the course fees.

The University of Bedfordshire charges students that already hold a degree at a higher rate, in line with the fee that international students are charged. My acceptance letter states the fee as:
Fee: £1775 per 15 credits (a full level of an undergraduate course equates to 120 credits)

This would make 1 year (60 credits) of the 6 year course £7100. But when I enter this into the field, I receive an error:
There is a problem
The amount of tuition fee you have entered is more than the maximum chargeable fee of £6935 for your course.

I'm not sure how to resolve this. Do I pay the difference myself? If so, that is fine, but I need some guidance for how to complete this part of the application correctly. I am still awaiting a response from the university for clarification, but any assistance here would be greatly appreciated,
Thank you.
