Syncing Zoho project meetings with Zoho Calendar App.

Syncing Zoho project meetings with Zoho Calendar App.

I am having problem syncing my Zoho project meetings with my Zoho Calendar App.  I have selected the same timezone America/Denver in both sections, but the meeting times are different.  I updated meetings in Zoho project, but the new times are not showing up in my Zoho Calendar App.  How do I sync, so that meetings show up on both calendars at the same times?
