Header Logo

I was trying to change our logo on the header to one that looks good in all modes (computer, tablet, phone).
I went to appearance-customize-Foundry Child Header Settings- Logo settings.
I removed the light logo and logo and added the new logo. But now my header is just blank. I even tried putting the old logo back and nothing. It will not show any logo.
