    This happened when you try to show something cannot show in Combobox. I prefer you copy the formula, create new combobox and paste it into the new one. After that, on the fields property, click on edit and add value field when the data tab is opened.

    Best way create a collection with distinct value and then call it in combo box. Use Clear collect if you need dynamic values.

    Hi,
     
    Power Apps loads by default 500 records into controls like ComboBox and Dropdown and it can be increase up to 2000 records in app settings.
     
    Try with this formula and if you need you can apply distinct to it.
     
     
    If(IsBlank(ComboBox1.SearchText), FirstN('DataSource', 200), Filter('DataSource', StartsWith('ColumnName', ComboBox1.SearchText)))
