Create a category, say "Income"
Create another category "Expenses"
Then you want to create subcategories for expenses, i.e. rent, utilities, etc
You can't.
The drop down box should default to a blank. But it defaults to the first category created and any other category after that becomes a subcategory of the first category
And the category "Expenses" becomes a subcategory of "Income"
