PROBLEM WITH DIVIDE -1

HELLO EVERYONE

I HAVE A PROBLEM, WHEN I USE A MEASURE THAT DIVIDES MONTHLY SPEND VS. THE PREVIOUS YEAR'S MONTHLY SPEND AND I USE -1, THE VISUAL, I HAVE AN ISSUE THAT SHOWS ME OTHER YEARS THAT I HAVEN'T SELECTED ON THE DATE OF THE TARGETING.

IN THE PICTURE, I CAN EXPLAIN BETTER, THE QUESTION IS HOW CAN I USE -1 AND NOT MISS THE DATE OF THE SLICER.

BEST REGARDS
