Programs Changes On LPD8

Need help on this one on Prog 2 I midi assign samples on pad 1 & 2 also midi assign 7 & 8. Now when I hit pad 1 & 2 the sample is not there but when I hit pad 7 & 8 the samples play but on the wrong pad. I tried to switch it back but keeps assigning or playing pad 7 & 8 and not pad 1 & 2 that is supposed.

I'm using it with Serato Scratch Live to trigger cue points, samples, effects and loops. Is there a way it an be fixed or switch it back to preset default ? Thanks !
