Tab_completion and auto_complete_commit_on_tab not working

[StephenS]

  "tab_completion": false,
  "auto_complete_commit_on_tab": false

I have got these two settings and tab-completion is still happening.

Are there any others that I should know about to disable completion on a tab press?

Thanks in advance.

Does this also happen in Safe Mode?

Yes it still does, I just unzipped a brand new portable version, installed any updates, restarted and added those two settings in the first post and this is the result after typing d and then tab.

I restarted ST after I applied those settings just in case that could have an effect.
