PGP Desktop Fingerprint with Duplicated values?

I just generated my PGP key the other day and I noticed something possibly odd.

I took a look at my fingerprint to see what it was and sone of the Keywords generated are exactly the same (see photo).

I looked at the hexidecimal version and assuming each 2 chars (based off of length and amount of words) gives a different word I shouldn't have any duplicates. (Because none of the hexidecimal numbers are duplicates.)

I know I don't understand how the words are really generated but I was wondering if this is a common occurence or if there should be anything I should be concerned about? My systems RNG etc?

Thanks for your help.
