appointments+ not syncing with google cal

i have had appointments+ for some time now and i have not really used the sync on google cal into this year and am now finding out that they are not working like they should. website to google works fine but google to website not so good. there is a 5 min delay for it to make it to the website but it only stays in reserved by gcal and does not block out time and does not allow any info for that to be entered on the back end. Is this Just the way this works or do i have a problem.

thanks jason
