Urgent Help! Invoices difference for Limited company

I submitted my T1 G extension some time ago. Yesterday, I found out the small errors on the invoices I submitted and those originally sent to employer.

1. Original invoices sent to employer for weekly work did not have invoice date, and I added invoice date for submittion.

2. Original invoices sent to employer did not mention the net amount, only the sum, VAT and gross total, invoice sent for visa had the net breakdown. gross amount remains the same.

3. Some of the original invoices were combined into one for visa and the break down and amount also remain the same.

4. As business travel is the same rate as normal work rate that it was mentioned in original invoice, and in those for visa, I included business travel hours under the working hours, and of course, the total amount remains the same.

Question: If Home Office conduct verification check with employer, and employer only provides the original invoice, will they consider those for visa invoice as faulse?

Any remidies? If I apply to withdraw, it will prob miss the 6 April deadline for re-application. Urgent help needed!
