Here is what I did to change the settings, a temporary work-around.
Those settings can be changed directly in the database using phpMyAdmin. If you do not have access or do not know how to access phpMyAdmin, check out the WP-phpMyAdmin plugin.

To make it easier, I am going to narrow down the list of options in phpMyAdmin so it is less confusing (maybe). You could skip the search step and find the options somewhere in the wp-options table, but there are 100's of options to look through.
In phpMyAdmin, I click the Browse button for the wp-options table, depending on what plugins you have you may need to scroll down to find the wp-options table. Once inside the wp-options table, I click the Search tab/link. On the search page, in the bottom five rows, the third row drop-down menu (option_name operator) I changed to "like %...%" and type "cc" (without quotes) in the value field for that row. Then click the "Go" button. Depending on the plugins you have installed, you may have to scroll down on the next page, but there should be about 15 rows that start with "cc" in the middle column. Those are the options.
Change the "cc_widget_show_list_selection" value to 0 to disable the list dropdown in the widget.
Change the "cc_widget_show_lastname" value to 0 to remove the last name field in the widget.
