task sequence not listed in software center

i create a TS to uninstall some software and install software as it needs to be done in a specific order. this has been working fine. i have a few systems where that is still showing the old software as installed. i looked at a few of the systems and i noticed that the TS isnt listed in Software center. this system has the this month patches and a new application that was deployed so it seems the client is healthy. Any suggestion on logs i should look at to see why its  not showing up?
