Od supplement

Just some minor changes. There is still some an issue with spacing when writing the file that is deployed to eospublic. See

/eos/opendata/lhcb/upload/opendata-lhcb-ntupling-service-dev/requests/41/outputs/test-production/mr-814.md

This causes the dropdown menu and the size estimate to not be displayed correctly. In local tests that was not an issue. I will try again after the merge, and think about it more thoroughly
