mogrt with responsive design time not working in Premiere Pro

Hello. I have created the attached lower third for a client and need to export it to them as a .mogrt for them to use.  I have been trying to get the responsive time to work properly in Premiere, but when I export it as a mogrt and import into the essential graphics template in Premiere, it does not maintain the protected regions / behave as expected in the timeline.  I have been searching for an answer for days.  Please help me get past this issue.  Thank you in advance!
