Beats out of sync

I think I am missing something obvious but can someone help. I have a project open (100bpm) and I want to drop in a loop from the loop browser. The loop I want is 101.989 bpm. When I select the ‘align beats with project’ button and and audition the loop all is in sync. But when I drop the loop in the project it reverts back to its original tempo and then becomes out of sync with the project? Do I have to audio warp to correct the beat or is there an easier method?
