Please accept my apologies. I was looking into this problem a bit deeper and realized that the reason your "Price" and "Marketcap" boxes are not populating is because the explorer currently only supports BTC markets when populating those values. I have added this to my TODO list and will add support for ETH and USDT and other markets in the near future. For now, you may want to hide those boxes via the config until a fix is released.
Thanks for letting me know. No rush, but do you have any idea about how long it might take for you to come up with this update?
