Error in E-verification for Form 35(Appeal)

I am trying to file/submit form 35 (Appeal) for AY 2024-25. After furnishing all details, it fails at E-verification stage after I enter Aadhaar OTP or EVC. The error message I receive is "Error : Please enter valid values.".

First, I entered details from the matter prepared in a MS Word document, then suspecting a special character to the cause of problem, I also tried entering details from a plain text document. I have removed the characters ( ) / from facts, issue, ground section of form 35, but no luck. Grievanve raised on the portal remains in 'Submitted' status for the third day. 

I would sincerely appreciate any helpful clue to resolve this issue.
