Wipro — Wipro Query related to Embark preoffer background verification.Mandatory field mobile number error

Resume Number: 24165037

I got Selected in the Wipro ELITE NTH 2022. I got mail from campus HR team from wipro to upload documents for background verification.
I have filled my personal details in the embark portal. I have got zero number i.e; (0) auto filled in Mobile number column as default so, I couldn't edit it.It particularly shows the error under mobile number column as "please enter your mobile number", When I click save and next button in personal details section it is showing "please enter mandatory fields" and due to this I am unable to save personal details and proceed to the next section for background verification.

I have accepted letter of authorization (in declaration) on 2 april 2022 and have been facing this issue.

I kindly request you to look into this matter, if possible edit my mobile number in mobile number column and resolve the issue as soon as possible
