I am using Mac Omnifocus 4 Pro now, and this bug has been persisting from Mac Omnifocus 3 Pro.
When I create a task in Mac omnifocus with normal text in title, some time it becomes a task with its title being null after it syncs with other device. At this this time the task title in Mac is null but this task in iOS omnifcois is normal. Nomatter how many times I manually do the sync action, Mac omnifocucs task still has null title.
Every time in this case, I need change the text in iOS omnifocus like just adding 1 number in this task’s title, after syncing, the Mac omnifcois can become normal.
I found this bug during using Mac Omnifocus 3 Pro and thought 4 pro has fixed this bug, but it seems this bugs still persists in Mac Omnifocus 4 Pro.
