Thank you that was helpful. Instead of going to "Receive" and copying that address, I went to a past transaction and pulled that address like you said. A balance DOES show up now but it's around half the balance in my wallet. Very confused.
As far as understand, every time you made a transaction, (sending out), if you are just sending part of the bitcoin holdings, the excess Bitcoin will go to another address created by the wallet. You can avoid this from happening by getting the private key of the receiving address and import it as solo address, this time every time you send part of the Bitcoin of the existing balance, the excess will return back to the same address because it is the only address available in the imported wallet address.
Though this might compromise privacy but then you will always see the whole balance in the same address when using a blockchain explorer.
