Permission issue

Hello folks.

I’m having a problem with the permissions. With the admin the plugin works great, all the functionalities and all the workflows works exactly how it is expected. Despite, when I try to use another role (system defaults o created for need), only the first field of the form is loaded.

I set just one worker, so the first step should be the room. When this is selected, the service field don’t load.
I tried to set just one room and the services loads at the beginning, but after select a service, the calendar don’t load.

I updated the plugin to the last version and the error is the same. There is anyone with a similar error?

Thanks
XAN
