your combo box items is from the collection. Try using lookup in the defaultselecteditems. This will help to find a complete record.
LookUp(YOurCollection, Name = "KOMATSU")
And regarding selected value as default until the app loads. Reset the combo box on then you it to get reset. In case of form, you can add that OnSuccess property of the form, but you can add it wherever you feel logical in your app.
Reset(ComboBox1)
