Expense reports including itemizations w/ conversion rate randomly not allownig to complete audit

Summary:

We have had some instances where user report they are unable to complete audit after reviewing an expense report that contains itemizations (such as a hotel bill) that have conversion rates attached to those lines. A small red 'x' next to the line after trying to 'complete audit' shows there are warnings - but upon reviewing there is not an issue and expense able to save correctly.

Content (required):The workaround we've seen is for either update the expense report status via API or the auditor can reject the report and then user submits again and is fine with no change to the report details (so we know that the report had nothing wrong with it as its able to complete the second time)
