You should keep it, as you can tweak it with the crown anyway. Mine has the same issue (Skyland), it is totally not worth sending it back for, and I doubt the dealer would agree anyway......
Plus the replacement would likely have some other issues anyway. I bet your watch has a nice clean dial and hands by the look of it, and an aligned/straight Breitling wings on the dial, which is a bonus with these reps
Just be thankful most of the dates are OK, and that it is not misaligned to the left or right, or too low, as then you would be able to do nothing about it via the crown
A service of the movement would not help, as the date wheel is printed slightly out, so it cannot be corrected....
Enjoy your BCE it looks like a sweet watch.....
Cheers!
