[Wien] fermi energy change

Dear Wien2k Users
 
After I finish the SCF, I try to calculate the bandstructure.
I add the k points to the Case.in1 file and run lapw1. After that, I run lapw2.
But in some cases, the calculated fermi energy in Case.scf2 after run lapw2 is not equal to the one in the Case.scf. 
My question is why the fermi energy changes when I run Lapw2. And also, in this case, which fermi energy should I input to Case.insp for bandstructure calculation.
 
I will highly appreciate your help.
 
Best Wishes!
