What to do with a blessed rosary that is missing a decade?

My neice recently purchased a rosary for my dying mother from a hospital (not catholic) gift shop. I had it blessed by a priest. I then discovered when praying a rosary on it, that it only contains four decades. I am reluctant to return it to the gift shop as defective since it has been blessed. Or, is it not really a rosary since it only has four decades? Please advice on the right thing to do.

Thank you,
Tina Castro
