Help with bitcoin gold fork explorer

So, I’ve some bitcoin before the fork happens. So I decided to check my BTG using this explorer that i found online https://bitinfocharts.com/bitcoin%20gold/

But when I check all my addresses that have BTG transaction it shows like this

Is that normal? or all my BTG had gone? Im using Electrum wallet and haven’t even moved my BTG coins since then.

Is there a way to claim my BTG coins?
