Rashba-like splitting at the VBM of Wannier band structure, but no splitting at the VBM of DFT band structure (same material). Any suggestions?

Dear all, I recently did DFT calculation and Wannier interpolation for the band structure of a janus monolayer (SOC was considered). In general, the obtained DFT band structure and Wannier band...
