Challenge log completetion warning

[Iscah]

Don't most of the logs give you a heads up that "[log] is almost complete."
I see it all the time for Bossom Buddies.

Do not all of them have this?

The warning appears but it pops up when you complete your fourth dungeon out of five, or whatever the task is. So if you do something inbetween or log off for the night after that, you may well forget by the time you decide you feel like running a Lv80 duty now.
