Incompleted form doalownded in excel file

Hello Commcare users, devolopers and support Team

The mobile users submitted the forms, but when I download the excel file, I don't see all the form submitted. I find recently submitted forms but, when somes forms submited since the morning are not availlable in the excel file.
In the tablet the status of all the forms are sent and I don't have internet problem
Your support please!!!
