Imported tasks

Imported tasks

Good afternoon, 

I have recently setup a test instance of Zoho CRM and am currently working through a data migration from Hubspot usine the API migration tool. I needed to get a feel for how seamless this process was but I am running into an issue. 

It looks like all of my prexisting tasks in Hubspot were brought into Zoho, tagged properly, notes, everything is in good order, including the due dates. 

But, when I look at the task list and select Today, next 7 days, or basically any sort of future time frame, even though I have tasks in the system that are tagged with a future date, they do not show in those lists. Now, if I create a new task within Zoho, the function works as expected. 

Is this a bug? Is there a work around?
