The list contains all input files used for the conversion. The main media file (loaded in SP) can't be removed. It also contains the first and second subtitle files (when selected). These also can't be removed.
The Add and Remove buttons allow to add / remove additional input files. This function is not yet implemented.
The check-boxes allow to add / remove first and second subtitles. If the check-box is disabled, it means, that the appropriate subtitles are not loaded in SP

The tracks can be enabled / disabled (when selected) by the Enabled check-box
