The only thing you should be using the Convert tab for is if you want to convert the LOR file to create an FSEQ to run on the FPP. If you want to bring in LOR data then in XL4 you should either import as data using a Data Layer or import as editable effects using Import Effects. It's kinda late in the season to be starting to learn all this though most of us are focusing on our own stuff now and I'm about to go off grid for over a week.
