Please note the message from WooCommerce and advise . . .
Your theme (Exoplanet Pro) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. You can see which files are affected from the system status page. If in doubt, check with the author of the theme.
WooCommerce offers a status report that I can send to you if it helps.
