Why does QBO keep changing my book's opening balance?

The FIRST LINE of my Paypal bank account register reads this:

Date: 1/1/2018
Type: Deposit
Account: Opening Balance Equity
Deposit: $2,722.87
Balance: $2,731.60

This just changed TODAY.

Yesterday, Deposit and Balance were matching.

How did this happen?
