Hello,
Please refer to this documentation: https://wpml.org/documentation/related-projects/woocommerce-multilingual/#taxonomies You need translate attributes in WPML > Woocommerce Multilingual > Booking tab.
Also you need add terms Reservation, Reservation 78, Reservation 79, Reservation 80 and so on to your attribute http://storage1.static.itmages.com/i/15/0511/h_1431357783_3847269_35b10162ce.png as you have written in products editor. Then readd attribute for a product as described here: http://docs.woothemes.com/document/variable-product/
