What's new still has old cards rotating through

[butlerpd]

Describe the bug
On my Windows machine, downloading the windows installer asset from github release page for 6.2.0a3, the what's new rotation has the new items but then keeps scrolling through the previous ones as well (so the slide with a summary of latest changes is followed by the slide on the size distribution which was first in the rotation for 6.1.0)

Expected behavior
Only the new slides should show in installer installed popup
