Adding a rental property paid for with cash

So I added a new account, asset, rental property. I put in 50k purchase price, 50k value.

I called it "J75".

All OK.

But when I go back and find the wire transfer in my checking account for the $50k and change the category to "J75", the value of the account in the account list on the right hand pane changes to $100k.

Is the correct way to do this, to reset the opening balance to zero?

Thx!
