wrong dafault Layout Template displayed by B1

Hi Experts,

I am having difficulty seting up my desired default Layout Template for Profit and Loss Statement. I go to Print Layout Designer and Choose Document Type and select the Document Type I want such as BPL1, BPL4, BGT5 and so on. In the Layout Template list I select one template and set it as default and try to preview the report. To my surprise, the layout of the report always goes back to a Document Type of - Profit and Loss Statement Comparison. It always uses the said Document Type - Profit and Loss Statement Comparison. Is there a way to enable the usage of other Document Types in the Layout Designer. I hope other Document Types are usable since they are dispalyed in the selection criteria.
