I understand the problem you are facing !
As mention by you actual order is already placed and there but as per the screenshot Dashboard is not updating and its statistics is not updating.
So logged in to backend -> go to the reports -> select all the reports -> from the action menu select - refresh stastics
then clear cache and check dashboard it will show updated order
For more details steps refer this link - https://docs.magento.com/m1/ce/user_guide/store-operations/reports-refresh.html
Hope it helps !
