Currently, if choosing to calculate ND with the 'phonological edit distance' algorithm, the option for a wordlist entry (.txt file upload) is only partially disabled -- you can select a file, but not specify what the file contains. I think the whole option should just be disabled for now, i.e., if you choose phonological edit distance as the algorithm, a .txt file upload is not allowed.
