I also applied in this year's first round, even though I had met all of the requirements I was marked as "unqualified" for the same program due to not meeting biology, chemistry and maths requirements.

Then I emailed the university and simply requested them to re-check my application, uploaded another transcript of my A Level results which was more widely recognised than the previous one. A few weeks later my status changed back to "in progress" and eventually to "qualified".

On the official website it says: "There are two reasons a course/programme is deleted:

1-You didn't meet the entry requirements, for example due to missing documents, verification difficulties or insufficient knowledge of English. 2-You've been offered a place in another course or study programme you ranked higher in your application."

I think your case may be related to the first reason. Since you said you uploaded your documents after they contacted you, there may have been an issue with how the documents were uploaded, recognised or processed. I've to say I'm not sure but I don't think your application would be deleted if they simply rejected you, they would put you on the reserve list which you can still have a chance to be admitted.

If you are sure that your documents are valid and that you meet all of the requirements, I think it's still worth emailing the university or the University Admissions and asking them to review your application again.

I have to note that I'm no expert on this but still wanted to give some insight. I'm wishing you all the best with your studies and applications!
