Hello @Hally_Bashor
Welcome to the Asana Forum 
The behaviour you have observed is the standard Asana behaviour; so yes, I can confirm it happened before.
Newly assigned tasks to you are automatically stored in the “Recently assigned” section, you might have renamed the section, but that’s the default name and it is a “special” section.
Depending on what you are trying to achieve, you can set-up rules to have the tasks moving automatically into other sections based on their dates for instance.
Cheers,
Rosario
