Then going back down to the smallest cog on the back it is fine. I’m guessing that is a index issue on the rear derailer? Also come to find out the seat this thing came with is quite painful lol. I guess I’m used to my mtn bike seat.
I'd suggest you increase cable tension a little to see if it helps. You do that by turning the barrel adjuster at the rear derailleur counterclockwise. Turn it a quarter turn and see if it changes the shifting. This could also be a bent derailleur hanger.
