Bell tech leaf springs b2200

Looking for some insight on bell techs lowering leaf springs for an 88 Mazda b2200. I installed them on my truck and ride quality is great. Problem is the rear seems to have shifted back about an inch or so and the shackles seen to have shifted to a flat position. Has anyone had this problem? If so what can I do to solve it?
Thanks in advance. Del.
