Can't find "Show all items immediately" in my RG

Hi
I am new to Bubble. I am trying to use PDFPotion plugin to generate PDF off my bubble page. But, when the PDF is generated, the repeating group part is not visible in the pdf.

I looked at PDFPotions help documents and there is an article asking me to check “Show all items immediately” on my RG. But, I am not able to find this property. Pls help.

You selected a fixed number of rows and columns. This is not available if you keep one of theses settings.
