[Wannier] In the plotting HSE06 bands using wannier90 code, I need help!

Dear Developers and Users,

I am Zimmi Singh, a Ph.D. student from the Indian Institute of Technology
Kharagpur, India.

For quite some time, I have been trying to plot the band structure of
monolayer VS2(semiconductor, band gap > 2 eV) using HSE06 functional and
wannier90. The DOS with HSE06 predicts a gap of 2.15 eV. However, doing
wannierization for the band shows no bandgap, and the graph shows
entanglement of bands (see the attached HSE band and dos plots).

I am attaching all input files of scf, open_grid, .win, and pw2wan.
Additionally, the DOS and band plots with PBE functionals are also attached.

Could you kindly check the files are help me figure out why I am unable to
properly disentangle HSE bands using wannier90?
