Check the Normal representation of the accounts in question by selecting the Accounts button > Setup and review the Normal Rep column. If the column is blank block the accounts (Block All) and set one account to Periodic (press F3 to select) and then isssue Tools > Fill Column to set all of the block accounts to Periodic.
From the columns where you have set your dates ranges, select a value in the particular column and press F11. Enter your begin and end dates and set Respect Normal Rep to Yes. This will show you the ledgers for the date ranges asked for.
If your accounts above have a normal rep set to Perpetual. Press F11 on a values in your columns and set the Respect Normal Rep to No.
Hope this helps.
