Chat Restrictions Not working as Intended.

I was recently chat restricted as the result of saying some vulgar things while I was drinking which I totally understand and accept, however in my chat restriction games my chat limit is not being added to at the set intervals. After my initial 3 messages I am not getting any at 4:00 or beyond which is making it impossible to communicate outside of pings for sometimes up to 30-60 minutes which is unreasonable and makes me appear to not be communicating with my team. I am just curious if this is intended and the message "Additional Message available at 4:00" is there by accident or if this is a bug that needs to be fixed.
