After any change of WooCommerce settings, the “Default Custom Template for product” value gets emptied. As a result, the default product detail page template is used again.
It’s about this setting: http://prntscr.com/k2u4w2, which should keep using this template: http://prntscr.com/k2u553.
Looking forward to the bug fix.
