Hello,
You are using Germanized plugin, this plugin doesn’t come bundled with our theme, but we added “Compatibility of built-in WooCommerce Email Builder with WooCommerce Germanized plugin Email types” in the latest update by request from one of our customers – https://xstore.8theme.com/update-history/ It means that you need to update the theme and Core plugin. If you are worried about the update, create a staging site (full copy of the existing one), can do updates there first. If everything is ok then you’ll be able to update the production site.
As was mentioned, by default there is no possibility to show the delivery time. If you are using an additional plugin that can show that time, follow this reply – http://prntscr.com/12comz8 If this doesn’t work, contact the support of your plugin first.
If after all these steps any assistance from our side will be needed, let us know, and we will check what can be done to help you. Please note, that our technicians team will be available after the weekend only.
Regards
