dashbord not loading all data

Hi

May someone please assist with this:

i have a dashboard thats running 12 months data and it was running fine until today, it started showing the last month data only and all the other months doesn't show, i went back to the query to check if its also showing 1 month data but thats not the case. The query shows all the months.

If anyone knows what could be the problem then please assist

Thanks

Lebo
