Printing Item Labels > Select Next Page > Notice: Data you entered on this page has not been saved and will be lost. Press OK to proceed.

Navigate to Transactions > Management > Print Checks & Forms > Item Labels. In the first page, select item lines, check some boxes under Print column and try to go to the second page.

There will be a pop up message saying: Data you entered on this page has not been saved and will be lost. Press OK to proceed.

This is by system design. The recommended solution for this concern is to print item labels per page or you may customize and use filters to narrow down item labels to be shown.
