SSRS Report : Data moving to another page (Set to A4)

Hi Everyone,

Can you please help me with this report in D365.

I created a SSRS report and there are 15 fields in it. I went to Report properties and made it as A4 with global standard size 21 and 29.7 .

When I generate the report in PDF only first 8 fields are coming on first page and remaining are moving to 2nd page.

Could you kindly tell what is the problem with this.
