Hi @kdrees21 ,
It may be because the default date format on the browser is not the date format of the native host and is not recognized, you can try the following:
Go to Setting in power bi service.
Select Language and check if your language setting is on "Default (browser language)"
Let's go to the browser to manage the date format, such as Chrome:
Enter Setting in the browser:
Click its language – Move to the top
Refresh your browser, then go back to the Power BI service opened in Chrome and refresh the page
