JavaScript Starting Episode Number Prompt Failing on KissAnime NZ

[mrama030]

Try to run script:
$.getScript("https://rawgit.com/aviaryan/Kissanime-Batch-Downloader/master/kissanime.js")

On:
https://kissanime.nz/Anime/ashita-no-joe.69389/

And putting 1 or 001 as the starting episode number fails everytime.
