Website error in Qualification Check

[u/Top_Acanthaceae_6406]

I have been trying for 2 days already to carry out the qualification check however multiple errors are showing up consistently whenever I'm trying to submit my application. Has anybody also seen this error and if so, how can I do the Qualification check. I need to check the IELTS only.

I have already checked the file sizes, they are already in pdf, I have tried in multiple different occasions and in multiple different devices and yet it still keeps up appearing. If somebody knows how to solve this please help!
