The "projections=ProjectOnTags" produce a wrong result in DOS(PDOS, fatbandstructure) calculation.
I set two different tags in my scripts. Then, I calculated their PDOS. I got obvious wrong results. The same the fatbandstructures are (see the attached figure). This error is believed to only occur in ATK 2019 (In addition, the other projections, such as "projections=ProjectOnElement" works well). Because when I test the same script in ATK 2018, I got the correct results.
