[HELP] - I can not work out why this update is "invalid"

[Jynks]

I'm having some real strange problems here... basically I have a working update.txt file.. but as soon as I change anything it no longer works for some reason as reads as invalid.. but it looks fine to me?

I have been trying to move my project to github for hosting... the not working update list is this one..

https://www.dropbox.com/s/r6lewu0rgoq5xkm/updatelist.txt?dl=1

the working on is this
https://www.dropbox.com/s/ztcq85d7szml0ny/updatelist.txt?dl=1

(this drop box link will not go into lackey btw... it is just to show you the file.

Basically they "look" identical... but the links to the phase images have been corrected and the date at the top has been changed.

Anyone have any ideas why this is not working? It is really frustrating!

(Changed both links to dropbox so I can continue testing on github)

Try changing the date from 23-08-17 to 08-23-17 thats the first thing that pops up for me

Also this url works as well https://dl.dropboxusercontent.com/s/r6lewu0rgoq5xkm/updatelist.txt I had issues with ?dl=1 on dropbox url's

Edit: just made a working one with the date change https://gist.githubusercontent.com/heihachi/1cb78f0bd7c6385498efadc8504f50da/raw/0566538289bc202988ee54705f539c5b8394a06a/updatelist.txt
