You have Send Audio for Midi track, this will take longer, best to uncheck that and just drag the midi in or use a Send.
So the "Script: Write take markers to all items on selected track source folder name.lua" will only work on the RT/RD using wav instructions (all the little separate items) it won't work on a rendered midi to wav file.
EDIT: there is also "Script: ReaTrak insert media cue to selected item active take wav source file.lua" that will write text into a wav file as a cue where the cursor is in selected item.
