How do I avoid blank page in BIP Report?

Summary

BIP Report prints a blank page when trying to print a subtemplate.

I have a requirement where I need to print a sub template based on a condition in a RTF template. Output is in PDF format. My main template  is in Landscape mode while the sub-template is in Portrait mode. I need to have a page break between the layouts to maintain the WYSIWYG format. I am currently using the condition as per the following link:

When the condition fails, the report is generated as expected without any blank pages. However, when the condition is satisfied and the sub-template is called, a blank page is printed for every page in the sub-template. Any pointers on how to fix this? Thanks in advance.
