I've collected about 5 crates and it still says
[05:27:21 PM] Task Updated: Lost Supplies (1/3)

Here's pics taken a few minutes apart due to battling in between

I found another one [05:40:14 PM] Task Updated: Lost Supplies (1/3)

After taking a look in the barracks I realized that I don't even have that as a daily task today.

I left the grove and came back and they all seem to be gone now, so I have no idea what that all was about.

Oh this seems to be happening for me too, it's been like this for a while but I didn't realize it until recently. It seems to always be like that though.

I know there was a glitch a couple of days ago where players who were in the barracks when a server update/maintenance was done had glitched spawns. When Krin fixed that, I believe another problem was found.

This could be related to that. Maybe during the maintenance or one of the fixes, you had this quest active, but when it was 'fixed' it was cleared from your daily tasks. But, there was still some left over spawns from when the quest was active?

No I don't think it's that, I realized that this has been happening for a couple of months.

Ah, okay, then I don't know what it might be :D I sort of slack on doing the tasks because, for me, it is tedious to go back to the barracks to obtain the tasks then search the LG to complete them, then go back to the barracks to turn them in..

It looks like the database just has left over coordinates for tasks even if you don't actively have that Task (which is why it's stuck at 1/3).

I would imagine that one you open them, or eventually once you pick the task back up, it will correct itself.
