Service Dropdown not displayed

Hi,

I have tried to add more that one service to a service provider on the worker calendar however when i enter the short code which should display a drop down menu of available services it doesn't work. Instead it just shows the first service which doesn't relate to the service provider.

to see this please look at

please can you reply asap

Many thanks
