Import of BTC BIP38 Paper Walet into Electrum 3.3.4 not working
The blockexplorer shows the BTC balance is still in the Paper Wallet and not in the Electrum wallet.


Here's my understanding of the relationship between wallets, keys, addresses, balances and explorers:

A blockchain-explorer generally shows total unspent amounts ("balance") associated with a bitcoin-address. Blockchain-explorers do not normally have any reliable notion of wallets.

Two or more wallets can contain the same bitcoin-address and therefore both wallets can be said to "contain" the same money (BTC).

Therefore if both wallets contain the same bitcoin-address, a blockchain-explorer won't be able to tell you that an amount is in one wallet but not in another.

A wallet can contain many bitcoin-addresses. A wallet that shows a "balance" is likely to be showing you the total of the spendable amounts or unspent amounts associated with all the bitcoin-addresses it knows of.

If your new Eelectrum wallet is not showing the same balance as a blockchain-explorer shows for a bitcoin-address, it suggests the wallet does not contain that bitcoin-address (or contains more than one bitcoin-address with unspent amounts, or is not fully synchronised)



A beginners guide to the Electrum wallet says 


  the Addresses tab ... will be hidden by default. To reveal it, select Show Addresses item from the View menu. 


Perhaps this can be used to verify that your wallet contains the same bitcoin-address that you are examining using a blockchain-explorer.

You can also check the synchronisation status:


  When the block count under “Blockchain” equals the height indicated for the servers you’re connecting to, Electrum will be fully synchronized
