Can't add BBC token to CEW

Hello ! BBC tokens were sent out from smart contract to my CEW address during distribution. But I failed to add BBC custom token in my CEW. When I put BBC smart contract address 0xe7D3e4413E29ae35B0893140F4500965c74365e5 ( when adding custom token in CEW )- it can’t fetch token size and symbol. When I put symbol and size - it gives error " no valid ERC20 token" or like this.
How to add this token to my CEW ?!

I also noted that in Token Balances section BEC and DEX symbols are present and always have “loading…” status. I tried Opera and Chrome browsers.
