woocommerce 3.3.0 Beta options

Hello Team

I tested your beta version 3.3.0
And I found one nasty thing related to options

I use your function woocommerce_admin_fields() for type – select. I’ve found that now if the keys are numeric this function will not save it.

In details:
file – “plugins\woocommerce\includes\admin\class-wc-admin-settings.php” function save_fields()

In this form everything will work well $value = in_array( $raw_value, $allowed_values) ? $raw_value : $default;

Please write me if you will use it in the new version. This can reset the settings of many clients (where this function is used woocommerce_admin_fields() )
