I attached a picture.
In the first figure, we see that the difference between bands is rather large. We see that electrons do not occupy all the energy levels from energy 0 to Fermi energy level. There are forbidden band gaps.
But in the second figure, I see that the electrons occupy everything from energy 0 to the Fermi energy level (so there are no forbidden band gaps like the first figure shows) So, what is happening?
