Placeholder image isn't replaced?

I noticed that my placeholder image is still up in the background and the network image loads on top of it for some reason.
Is there any way to entirely get rid of the placeholder image.
(You will notice in the attached image that my placeholder image is still in the background and ironman has loaded on top of it instead of replacing it)

Start by reproducing the placeholder and network-image layering shown in the attached image, then trace the image-loading entry point responsible for displaying both images. Determine why the placeholder remains visible and verify that the completed behavior shows only the network image.
