Database Errors Upon Saving Settings

I have updated a couple of sites to the latest version (4.2.3) and both are exhibiting database errors whenever Captcha settings are saved:

WordPress database error Unknown column 'wp_cptch_packages.settings' in 'field list' for query SELECT
		<code>wp_cptch_packages</code>.<code>id</code>,
		<code>wp_cptch_packages</code>.<code>name</code>,
		<code>wp_cptch_packages</code>.<code>folder</code>,
		<code>wp_cptch_packages</code>.<code>settings</code>,
		<code>wp_cptch_images</code>.<code>name</code> AS <code>image</code>
	FROM
		<code>wp_cptch_packages</code>
	LEFT JOIN
		<code>wp_cptch_images</code>
	ON
		<code>wp_cptch_images</code>.<code>package_id</code>=<code>wp_cptch_packages</code>.<code>id</code>
	GROUP BY <code>wp_cptch_packages</code>.<code>id</code>
	ORDER BY <code>name</code> ASC; made by do_action('bws-panel_page_captcha'), call_user_func_array, cptch_settings_page, Cptch_Basic_Settings->display_content, Cptch_Basic_Settings->display_tabs, Cptch_Basic_Settings->display_general_options, Cptch_Basic_Settings->add_pack_list_input

Indeed, my cptch_packages tables do not have a settings column. Should they have this column, or is this possibly a Free vs. Pro issue? I am using the free version.

On a side note, please don’t set the plugin to change my settings upon update. On certain sites, I am using Captcha only on one or two forms (e.g., WordPress Login form, WordPress Registration form). Sometimes when I update the plugin, it automatically checks all forms.
