Missing band in Sentinel 3 data


In the process of bulk downloading Sentinel 3 data of the central Mediterranean region, I have found a dataset that appears to have missing bands:


This dataset has 4 fewer files than all others I downloaded, including band S8 nadir view (“S8_in”). These same files are missing if I download the dataset manually from scihub as well.

I have not been able to find a reason for the missing data. This seems abnormal. Is there a procedure for reporting missing data such as this, or is it something to be expected from time to time?
