The way that certain strings work on certain basses and some don't is somewhat of a mystery to me.
On my Fender Mustang I have tried Fender short scale 95-40(only gauge Fender do then in) Daddario and Ernie Ball short scale strings both in a more standard gauge (105-45 or 105-50, I can't remember) all of which have not quite sounded right.
Of the short scale sets the Fender set sounded the least meh so I ordered a 105-45 set of long scale Fender strings with the intention of cutting them down to fit, I put them on and all of a sudden that bass came to life,
Strange how that works
