Hi Tarron,
If that option is not showing then it is either not a regular text menu item or Bitdefender is adding it into the context menu in some weird way.
You could try closing OC, editing onecommanderv3.json from \settings folder and changing line
"ShellContextMenuSyncCascadeMenu": "False"
into
"ShellContextMenuSyncCascadeMenu": "True"
I am not sure how that affects individual items and if it would make a difference. It may take longer to open menu, so if it doesn't work, better revert it to False
