Time supervision is preventing allowed contacts during blocked hours.

This is on an Android phone, version 4.4.4 (Samsung Galaxy Core Prime)

Whether I setup an hourly allowance or a range of blocked hours, once the phone is blocked, my son cannot use texting or phone with allowed contacts. When trying to open phone or the stock text app, he gets the Norton Family "blocked" screen that can only open the list of house rules, or close back to the home screen. (screenshot attached) My understanding is that this should be allowing him to access the allowed contacts. Once blocked by time, that same screen is given for any app opened.

Please advise on what I am missing on this as it is one feature that must work. If blocking the phone for time prevents any contact, then there is no point in having the phone!

Thank you for the help.
