When creating a memory by clicking the 'add item' button on the bottom right, the
Item Style drop down tab at the top right allows you to click on, showing all the other item styles tabs.
This functionality of clicking the drop down is not available in any other screen, thus when you open the tab, then press 'cancel' at the lower left, the drop down will remain open with no way to properly close it, even if you click on the non-existent drop down arrow, or on any other part of the screen(to remove focus).
This will persist throughout the 'item navigation' screen and the 'add notes' screen, until the user clicks 'exit' or clicks 'preview', or goes back to the original screen, presses the 'add item' button, then clicks the drop down.
