TinyMCE Default Toolbar Not Applied

Epi 11 TinyMCE v2

Hi I'm having an issue configuring the default toolbar for TinyMCE, using the simplified example below the formatselect dropdown is applied OK but the toolbar still contains the default buttons/options

config.Default()
  .AddEpiserverSupport()
  .Toolbar("formatselect cut copy paste")
  .BlockFormats("paragraph=p;")
  .Height(300)
  .Width(580);

If I apply the same settings to a specific page and property it's renders as expected

config.For<StandardPage>(t => t.MainBodyContent, config.Empty())
  .AddEpiserverSupport()
  .Toolbar("formatselect cut copy paste")
  .BlockFormats("paragraph=p;")
  .Height(300)
  .Width(580);

I can't see what I'm doing wrong for the default setting which I need to apply globally

Thanks,

Jason
