MS Access checkbox triple state property

Question

I know that I can disable the MS Access Checkbox's triple state property from the checkbox's property sheet.

By setting it to false a user can only select either true or false as the value for the checkbox.

However, everytime the form opens it looks like the default state is selected which looks something like this:

I think this is rather confusing for a user as this default state looks like the check box is already selected. Is there a way to make the checkbox start as blank or false?
