Dear Seema,
I have not seen any issue like this in any of the following tool Report Builder, Sitecatyst Adhoc reporting and Workspace but just an assumption, are you taking report for July 2019 below like this? If yes, then it will show only till (current date -1). the below case i taken for july and the data populates only till 18th July 2019. However, if you did not point the issue like below then i wonder how it could be!. I apologies if my undersating is wrong.
Can you share more detail or screenshot?
Regards,
Kumararaja K
