Problems with Dmol3 Density of States

Dear all,

I am carrying some all-electron geometry optimization calculations on Dmol3 using GGA PBE with DNP and spin polarization and getting strange results. For more than one structure I get finite density of states INSIDE the gap. I can't explain this and neither can find the problem in the calculations (reran them with very high precision but the problems persists). Is this a common problem?

Sincerely,

Eric
