Oracle internet expenses - unable to see additional details under Internet expenses auditor responsi

Hi, can someone please be able to help. We are in the process of customising an internet expenses build in one of our oracle test environments for release early in the new tax year 17/18. I have found one slight issue. A user submits a claim for mileage, subsistence and expenses. They have added additional information which can viewed by clicking on the details box on the line level.  When the auditor goes in to approve the claim they can see the additional information entered on the expenses line but cannot see the additional information on the mileage and subsistence
