Unmatched ID of Players in VCT CN Kickoff

From VCT-CN official game UI and post-match summay, here are some unmatched player ID used in VLR:
(format is VLR ID: correct player ID)
'SWERL': 'Swerl',
'Autumn': 'autumn',
'coldfish': 'ColdFish',
'Yosemite': 'yosemite',
'deLb': 'DeLb',
'CB': 'cb',
'B3ar': 'B3Ar',
'QiuYe': 'qiuye',
'Bunt': 'bunt'
I would like to use some VLR data to do some analysis, but found following unmatched cases. Hope I could get some feedback, Thx a lot!

bump cuz idk what this means and i wanna help

i dont know what this means
but lets bump it anyways!

edit: i know what it means now, its saying that the ID in game does not match the UI on stream.

What does blud want

My guess is that they changed names when they switched severs to the Chinese National one (which has a completely different client etc.) but honestly idk.
