is it too far foward

i bought a saddle which was fitted by a saddle fitter, however a couple of days later the saddle was raising up and hitting by bum then both saddle and me would then hit the my horses back, i got the saddle fitter back, she said it was because my horse had bad conformation and that the saddle is the best fit i would get, i demanded my money back and got a different saddle fitter out, it was slightly more expensive but worth every penny, my saddle now stays where it is meant to. while waiting for your saddle fitter u could try using a front raiser pad, which should be ok used short term
