Symbols on silk layer
You have some component symbols that are placed outside the board, and under other components. If you disable the F.fab layer, you can see everything that actually will be printed to the board. You can also go into the 3d viewer (alt+3) to se how the finished board will look. Look at TP6, and all the arrays of capacitors you have. You can place these labels below the components if you want, or if you dont have the space for that on the bottom layer of the board, underneath their corresponding component.
