Green Dot (connected), correct addresses and no history... that's weird.
BTW, First (your reply to bL4nkcode) and Last (your reply to me) responses were inconsistent.

Is the "block_headers" file in the %appdata%/electrum folder's size is greater than 44mb?
If it still isn't, just leave your Electrum open for a couple of minutes or an hour specially if your internet is too slow.

Also, you said about "don't know when you've lost your Ledger"... Was this before January-March 2018?
If it was, what kind of "Bitcoin" was deposited in your Ledger? Bitcoin [BTC] or Bitcoin Cash [BCH]?
Electrum only supports Bitcoin [BTC].
