Report pulling through new added drop down list



I have a number of reports where I have added additional drop down selection options but when i try to add these to existing reports they do not come up as an option

Report there is no Feasibility/Design status to add

This is the source sheet i have removed Design and replaced this with Feasibility/Design

How do i get the report to link to the current source sheet and not a historical version, I though the system worked in real time?

Thanks for any help you can provide
