I am also an academic user, who has been experiencing the same issue.
Like Omar, I generally partake in five separate polls each week, usually in a sequential order. This means that I have to log in each time I want to use each poll (as the two oldest ones will have disappeared from the list of Recent Presentations by the time I want to use them again). This negates the utility of having saved Recent Presentations.
A better solution could be to have a scrollable list of 5-10 Recent Presentations.
