Hello Willi Van Boven, 

Thank you for your purchase. 

There isn't an option to remove the employee selection in the booking process, but you can hide it with adding custom CSS. 

Please try adding this format HTML to the page where you have your Amelia shortcode : 

<style>
.el-form-item.am-select-employee-option {display:none;}
</style>

and let me know if it helped. 

You are welcome, Willi. 

Unfortunately, it isn't possible to remove the Any employee option in Amelia with its current built-in features. The employee selection can't be mandatory and if no employee is chosen Any employee is the default option - a random employee is added to the appointment.
