Sorter global inbox truncates file names to 32 characters

When dragging files with long names to Sorter to put in Global inbox, the long file names are truncated to 32 characters (which is not what I want).

Curiously, this truncation does not seem to occur (full file names are imported) if I drag the files to the Sorter to put in a specific database in-box (not the Global inbox).

Is there a way to stop the Global inbox from truncating the long file names?
