Is drum rack doing something to my samples?

As the title suggests, is drum rack altering my samples or am I loosing my mind?? I swear to god, when I drag a sample into the rack from the browser it sounds slightly different, both in tone and length, just slightly, with no warping enabled, it’s driving me crazy. Or is the browser warping when previewing samples and drum rack is playing them raw?? Help pls. Notice this most so on kicks and snares
