Doesn't thoroughly shuffle

I have an Anki Deck of ~ 2700 Spanish words and their translations.

when I shuffle, the first 200 or more (I haven’t gone farther) are only from A through C of the alphabet. How can I get it TRULY shuffled so that ANY letter is random to bring up and review?
Would appreciate help from any Forum member or the Author

Set the New card gather order option in the deck options to Random notes/cards.
