What are possible causes for when the Method Editor DA tab is empty or blank?

If you are in the Method editor section of MassHunter Acquisition and the DA tab is blank with Qual or Quant tabs available, it may be the Region and Language settings have been changed from English US.

This is an error that can occur if the computer 'locale' is not US. In this case the Region and Language format were set to English (UK) instead of English (USA).
