Hi, i'm using the current version of your amazing plug-in, but i have the problem, that new added custom field tags are empty. In the Mail Notification tab following is showed: Available tags: #id#, #date#, #start#, #end#, #status#, #created#, #price#, #ip#, #link_confirm#, #link_cancel#, #url_confirm#, #url_cancel#, #service_name#, #service_duration#, #service_price#, #worker_name#, #worker_email#, #worker_phone#, #location_name#, #location_address#, #location_location#, #email#, #name#, #phone#, #description#, ##, ##   I've tried it with the label name, but didn't work in the email. I've also installed and run your plugin in several languages (en us and de) but it is always the same result.   Do i have register the tags tags or something?   Thanks for help!
