[CP2K-user] [CP2K:16639] Al2O3: Negative gapped with CP2K?

[Nicholas Winner]

I recently ran a calculation of beta Al2O3. This compound has a reported 
GGA gap of ~3eV (https://next-gen.materialsproject.org/materials/mp-32591)

I ran a static calculation on the structure from the link, and the 
resulting band gap was -0.02eV. I'm at a bit of a loss as to why this is. 

I've attached the input/output, and one of the PDOS files. Any ideas?
