FDX format compiles line spacing incorrectly

When compiling a screenplay as FDX, the line spacing is exported as a font point size, rather than the number of lines.

The FDX format is 1 for single spaced and 2 for double spaced, whereas Scrivener exports it as 12 and 24 respectively. Some screenwriting software can’t handle this error and will import a single spaced file as double spaced, meaning it has to be manually corrected each time.
