Electrum testnet wallets do not display the trading record for the address.

I apologize for the basic and foolish questions because I first encountered this business. I tried to find information, but I couldn’t do it.

I have sent multiple transfer to the address shown in the following example.

I also have this transmission in my history, and they are marked as successful. For reference, I moved from the wallet to the address connected to the wallet.

It is also connected to the test network.

As you can see in the wallet, everything exists and everything is okay, but there is nothing when trying to check my address.

Here, I checked the address through a special site.

I wrote a small program to confirm the history and balance of the address, but nothing is displayed.
