Cannot see old balance after using "Reset Wallet" [Trezor]

[mat888]

After resetting the wallet on the Trezor wallet page of the block explorer, the XSN balance that was previously shown is now 0, and no obvious way to get the page back to its original state or show the true XSN balance of the device.

Expected behavior

I expected that unplugging and plugging the wallet back in would reveal the balance there before hitting "Reset Wallet," but that did not work. Adding new wallet addresses in hopes of recovering what address the old TX's were sent to also did not work, but did reveal some strange behavior (mentioned later).

Steps to reproduce the behavior

Hit "Reset Wallet" to remove receiving addresses from the browser cache. The displayed balance should now be 0.

Original post in Discord with more information:
Okay, getting some strange behavior. I opened in incognito tab and added addresses to the Trezor Wallet tab in block explorer. The first addition put my balance from 0 to 0.00004... which was expected, but subsequent address additions did nothing - was hoping it would reveal the ~ 0.3 xsn that was there before I reset it the very first time.

Next I reset the wallet in my main browser window and started adding addresses. The balance started greater than 0.00004.. and every addition adds more. I'm at 0.00029... I've done this about 7 times, but the UI seems to be bugged and isn't showing any addresses.(edited)

Simply refreshing the page fixed that, and also added more xsn to the balance.

Adding addresses no longer reproduces this behavior, but the balance is still much lower than the expected amount. It is currently 0.00029 and should be about 0.3.
