Business Reports missing Revenue

My business reports are missing some revenue today. I have never experienced this before. The number of units is correct but a large chunk of revenue is missing. We made an FBA sale this morning for 11 units of a product and the number of units are correctly showing on the report but the revenue is roughly £37 short - that's more than 50% of the revenue for this sale.

Has anyone else experienced this? I'm not sure how concerned to be as this isn't the report that Amazon use for payouts, but if this revenue is missing here it could also be missing from other reports.
