General Ledger Transactions

Hi all perhaps someone else has had this problem:
I am trying to get General Ledger Transactions for the last financial year, I have the date set 1/7/19 - 30/6/20 however it will not show prior to September 19.
I have checked and double checked all the parameters to no avail, it appears there is a period lock or something else
