Meeting TOPIC change will not update REGISTRATION page meeting name

I changed my Meeting TOPIC to a new name. I saved it. I went back to the lisst of meetings and it is changed there in the list. When I click to go into edit the meeting, the name is correctly changed. 

Now when I go to the meeting REGISTRATION page, the meeting name is still the old, previous, incorrect name.  

The meeting TOPIC is not updated on the REGISTRATION page

How can I get the REGISTRATION page to update correctly.
