List on left side OK

When you select a graphic from gallery for a data point in a chart, or when you set the bullet type to graphic from gallery in the numbering dialog, then you get a list to select the graphic.

This list get its values from the "Bullet" theme of the gallery. This list is so long, that it does not fit onto the screen and you need to scroll. At top and at bottom of the list, there should be a triangle to scroll.

When the dialog is positioned on the right side of the screen, so that the list is forced to show up left, then these triangles are there and you can scroll the whole list. If the dialog is positioned default, which is on the middle of the screen, then the list is shown right. In this case the lower triangle is missing. Scrolling with the mouse wheel is possible, but unfortunately not to the end of the list, so that not all list items are reachable.

The attachments show this both situations.
