I recently found this piece on the internet after hearing it and decided to give it a try and learn it, so far this is a fun and challenging (for me anyways!

I'm having an issue with a chord that seems to be a typo in the piece. On page 3 of the piece, last measure before the repeat (so 4 measures in), the last left hand chord shows F#,D#, A natural played along with A natural on the right hand and a D natural on the pedal. This combination sounds very odd (especially against the D on the pedal) and makes no musical sense, at least to my ears it doesn't. I've listened to the song several times and figure what's marked as a D# in this left hand chord is an error and it should actually be a D natural instead, so the chord would then correctly be F#, D natural and A natural. What I'm thinking is they meant to mark it as the F was again to be sharp, but they incorrectly marked as the D to be sharp.
Could someone clarify this for me?
Thanks!
