Trying to add AdBlock Lists in DUMAOS.

So I am trying to add adblock txt files I got from Github. 

This type of lists

and I've tried domain only lists

But none of them can be added. The blue bar would go from left to right, as if it was finished uploading. When I click Add, nothing happens. It does not add the file to the list. 

Is the FILE method also limited by file size? 

Trying to add them manually through file type 'Domain' I find that there's a character limiter, as I can only fit about 61-64 domains each time. This lead me to think maybe the file (.txt) is also limited to file size. So I've tried to make my own file with only 2 domains. I get this error. Then I thought maybe they need to be in "strings"; and end with semi-colons. That wasn't it either. I can't seem to Add Files. I get the error:  "TypeErrorerrorMessagestartsWith" is not a function.
