Error in Coupons

I am trying to add/edit my coupons and I am getting this message:

Fatal error: Uncaught Exception: Invalid order. in /home/customer/www/bakertargets.com/public_html/wp-content/plugins/woocommerce/includes/data-stores/abstract-wc-order-data-store-cpt.php:137 Stack trace: #0 /home/customer/www/bakertargets.com/public_html/wp-content/plugins/woocommerce/includes/class-wc-data-store.php(159): Abstract_WC_Order_Data_Store_CPT->read(Object(wf_order)) #1 /home/customer/www/bakertargets.com/public_html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-order.php(130): WC_Data_Store->read(Object(wf_order)) #2 /home/customer/www/bakertargets.com/public_html/wp-content/plugins/ups-woocommerce-shipping/includes/class-wf-legacy.php(37): WC_Abstract_Order->__construct(11975) #3 /home/customer/www/bakertargets.com/public_html/wp-content/plugins/ups-woocommerce-shipping/includes/class-wf-legacy.php(32): wf_order->set_order(11975) #4 /home/customer/www/bakertargets.com/public_html/wp-content/plugins/usps-woocommerce-shipping/includes/class-wf-shipping-usps-admin.php(3775): wf_order->__constru in /home/customer/www/bakertargets.com/public_html/wp-content/plugins/woocommerce/includes/data-stores/abstract-wc-order-data-store-cpt.php on line 137
