Urgent help for background check requirements

I officially left my previous organization in October 2023, but I actually worked until December 2023. I was going through a financial emergency and requested them to pay November and December month salaries in October itself, to which they complied, and did my entire full n final clearance in October itself.

Unfortunately, the finance team made errors: my end of service date in the PF account is listed as October, and there were no tax deductions nor PF paid for November and December, also causing issues with my pay slips. My experience letter correctly states my last working month as December. I've tried to rectify the situation by asking my previous organization to update my end of service date, but due to the missing PF deductions, it will not be possible.

Now i am joining a new org and i am afraid i will fail the background check cz of all this and they are demanding for last 3 months payslips while i have payslip only for october which includes Salary till December under “other prerequisite”

Please advice on a way out. I do not wish to lose opportunities due to this situation.
