PRINCE creating dups

[forumhero]

for example i have a wordlist containing the following:

Code:

my
password
is
the
best

but i get a lot of dups even though the wordlist itself has unique words:

Code:

mypasswordisthebest
mypasswordisthebest
mypasswordisthebest
mypasswordisthebest
mypasswordisthebest
mypasswordisthebest

hashcat-cli64.bin -a 6 --stdout example.dict | wc -l
124184
hashcat-cli64.bin -a 6 --stdout example.dict | sort -u | wc -l
113987

any way to de-dup this?
