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.
