Missing transaction in document journal report with Transaction Code

Dear Experts,

I am facing below issue when generating Document Journal Report from Financial --> Financial Reports --> Document Journal

1. When I run for 1 month report without selecting any transaction code the result is 1466 pages.

2. When I run for same period i.e. 1 month and click on expanded option to select all transaction code i.e start from blank to the last one under the result is of 45 pages only.

Please advise why selecting transaction codes removes so many entries.

Thanks Deepak.
