Hi Ilias,

Thanks for reaching out to us. Unfortunatelly, the only workaround would be to hide the strings with the custom CSS code. I went ahead and booked a test appointment, so i can "tag" these elements and provide a CSS code. You can use this one 

#amelia-container > div.am-fs__main > div > div.am-fs__main-content > div.am-fs__payments > div.am-fs__payments-price > div > div.am-fs__payments > div > div.am-fs__payments-services-open > div > p:nth-child(1) > span{
    display: none!important;
}
#amelia-container > div.am-fs__main > div > div.am-fs__main-content.am-fs__congrats.am-fs__main-content > div.am-fs__congrats-main > span{
    display: none!important;
}

Custom code needs to be applied to the page where the booking form is. Depending on what you're using (Gutenberg blocks, or some page builder), adding the CSS or JS can be done in a few different ways. 

If you need help with adding custom CSS to the page, please take a look at this article.

Of course, you can go ahead and delete this appointment.

Well, in that case, you can also try that approach. 

You are welcome, Ilias.

Should you have any other questions or issues, please feel free to reach out to us a new ticket and we will kindly provide assistance.

Have a nice day!
