Dear Bhamu, In most cases like this, the problem is that the physical model is wrong.
I am not 100% certain, but I very strongly suspect that the issues are related to the valence states of the Pr, Zr and Mn with the Pr being the worst. With the setup you used I am almost certain that the 4f of the Pr is causing problems, and without either -orb or -eece the states will sit at the fermi energy and mess everything up. Straight GGA for 4f is a disaster. You also have the problem of what magnetic ordering is relevant. I suggest that you first check (look up) the relevant magnetic ordering and 4f of the compound (literature + PrMnO3 calculations) and use either -eece or -orb for the Pr and (perhaps) the Mn. You can then setup the appropriate doped structure with close to the right occupancies/ordering. If it is Zr(III) in the doped compound then you will need -eece or -orb for the Zr.
