The album is pretty mediocre so 75k is actually not that bad, and she did zero performances which are the best type of promo.
She Wolf had way more promo, a much bigger lead single, came out in November, and 4.5 years ago when sales were higher and she's only going to have a 15k-ish decrease
I wonder why female artists can't pull any numbers out of stints on The Voice. It happened to X and now Shakira. All the male judges get hits and album sales out of it
