After did bitcoin transaction. I've checked my balance in Electrum wallet shows correct but in BitRef its display significantly higher transaction amount.
Is it normal? What is my actual balance?Balance on bitref or balance from Electrum?

When I tried to send BTC I open up the preview page
Outputs show 2 target addresses
one is the actual transaction another is very high amount
like

[target address]  2.
[another address with yellow highlighted] 246.29

actually I want to transfer 2.0 but in the inputs
show 248.29
and the Fee show as 0.0000526

What is the other address if the transaction fee is not that high
