Button to change woocommerce colors has gone

Hi there, At this moment I use two pro themes (catch store pro and Travelore pro). Changing colors of woocommerce with the catch store pro theme is no problem. In the Travelore pro theme, the button to change the woocommerce colors I cannot find. The Url is staging.toerfietsleusden.nl. "Appearance > Customize > WooCommerce > WooCommerce Color” doesn’t show the button to change colors. Also there is no other button to change colors somewhere else in the theme or the theme options part. Kind regards Hans Hagmeijer
