I have a list of 18k rows, and about 7.5k are known duplicates. The delete duplicates button will not delete the duplicates (except it keeps returning 41 duplicates for an unknown reason, but there definitely thousands more it is missing). I tried the remove duplicates button, advance sort, coloring cells, and some macros. The list is the combination of two lists, one older one just compiled, I was able to seamlessly delete dups in another list.

Why is Excel not recognizing my duplicates with the remove duplicates button or any other method??? Is there any solution to this problem?
