EDITED: I am trying to replace a dropdown with a Combobox. The Combobox is working fine with a default value, but, I am unable to use that default value.
ComboBox Items: Sort(Distinct(Holidays, Country), Result, Ascending)
ComboBox DefaultSelectedItems: [If(!IsBlank(Office365Users.MyProfileV2().country) && Office365Users.MyProfileV2().country in Distinct(Holidays, Country), Office365Users.MyProfileV2().country, "")]
If I do CountRows(ComboBoxCountryFY.SelectedItems) I get a return of 1. So there is one item in the Combobox. In trying to set a label (for testing purposes) to the value of the Combobox, I don't get anything.

ComboBoxCountryFY.Selected.Result returns nothing
ComboBoxCountryFY.SelectedItems gives an error
ComboBoxCountryFY.SelectedItems.Result gives an error
First(ComboBoxCountryFY.SelectedItems.Result) gives an error
First(ComboBoxCountryFY.SelectedItems).Result doesn't give an error but also doesn't return anything
I am out of ideas.
