Why I cant see the conversion on dashboard after a purchase ?

Conversions are tracked based on two variations as per below:

a) Real Time Tracking - Offers with this type tracking tracks conversions based on real time and you can see the conversions pending on your "Conversion Report" as soon as your user made a purchase
b) Manual Tracking - Conversions are tracked, however it is not based on real time meaning there will be slight delay in the conversions showing up on dashboard.
Conversions will be manually uploaded based on a specific day which is stated on the offer description page.
