My Work is Incomplete - Missing Assigned Tasks

I am new to Monday and I’m having an issue with the ‘My Work’ view. I’ve customized the view to include both myself and my colleague. Most of my tasks are appearing, but many of hers are not. I’ve double-checked that they are assigned and they have a due date, but are still missing from this view. Is there something I’ve missed or that I am overlooking? Thanks!

Are the due dates set up in deadline mode, and have you gone into the settings to check what boards are set up to feed into your “My Work” items?
