Can not select time on Appointments after Word Press Update to 4.5

Updated Wordpress to 4.5, on appointment page (using shortcode) I can not select the time, mouse indicates its selectable but no response.
Can change day and month.
Example shortcode used to open appointment page
[app_monthly_schedule worker="3" service="99"][app_pagination month="1" step="1"][app_confirmation title="Check your details" button_text="Click Here to Complete"]

Also does not work on Make An Appointment page.
