English

I have a question.
I will postpone the payment to HMRC until it is solved.
The question is as the following.
You said my payment was £3,875.08. But isn't the correct payment £3,875.02?
The formula is as the following.

And the first email from HMRC said the amount was £3,875.02 as the attached file.
However, the amount increased to ￡6917.34.
Why did it increase by £1883.68?
Did HMRC make a mistake in the calculation first?
