Is there a way to get app opening animations? I can’t figure it out

Bug Report

Device: Samsung Galaxy Tab 4 7″

Android version: 4.4.2 KitKat

When viewing menu for an item in a panel with horizontal only scrolling, snap to page disabled, and seamless mode enabled, some items dissapear until I close the drop-down menu for the item.

I have determined that the items that dissapear are items that would not be viewable if seamless mode was not enabled in the panel settings.
