Why are there no left and right buttons even though the banner has two images, and why can't I click the dots?

1. Under “Banner” on the left, check the “Manual Image Switching (Show Left/Right Buttons)” switch. It is currently off, so the banner only cycles automatically. The dots only indicate the current image position and cannot be clicked. 2. To let buyers and visitors switch images manually, turn on “Manual Image Switching (Show Left/Right Buttons),” then click “Upload Changes.”
