Custom Wordlist Error

[turbulence]

I am trying to make my own custom wordlist. I have ran into a problem that could be potentially hazardous. When trying to separate out a list of only 5 character words, I found a problem with the list itself.
I ran the command

cat wordlist.txt | pw-inspector -o wordlist2.txt -m 5 -M 5

The new list only displayed words that appeared to be 4 characters long. Thinking this might have been a error in pw-inspector, I generated a quick list with crunch and the pw-inspector worked just fine. So I assume this means I have some kind of extra character at the end of each word. This extra character will probably cause the wordlist to be ineffective when cracking.

Info on how I created the wordlist:
Downloaded 12dict dictionary from http://wordlist.sourceforge.net/
Combined the lists and made unique with

cat list1 list2 list3 | sort -u > wordlist.txt

Used a custom grep script to duplicate words with hyphens as words without.

When I open the list with

nano wordlist2.txt

I get the message at the bottom that it was converted from DOS. Could this have something to do with my problem?

So how can I identify the problem and fix it? I have attached a sample of the list.
