Hi @ahmad,
For both of those cases, we previously only had band gaps from static calculations. The new data set has some additional calculations, including more calculations along the key symmetry lines in reciprocal space. This is a better type of calculation for determining band gap and for both of these materials those calculations have determined that the gap closes somewhere along the high symmetry paths. We’re currently troubleshooting an issue where our build system is plotting some bandstructures, but we will fix that soon and you should be able to see the corresponding bandstructure.
