Assingned User not showing Second Task

Hello all

May be this is small issue but m not getting why is is happening. When i create First Task for any account and assign to any user it shows value of Assigned User value in “Activities” Subpanel but when i create another task for the same user and assign to any user then Assigned User field value is not showing in “Activities” subpanel. why is it so ?? Anyone ??

Are you still having issues with this?

Im unable to replicate on a local 7.10.23 instance.

When you create the 2nd task, does the task record get successfully created?
(ie, can it be found in the Tasks module?)

If so, is it related to the correct Account/User when viewed here?
