Unable to find the node for custom world subsystem

Hi All, I need some help. So I created my own subsystem, made it blueprintable so that I can create a blueprint class of it so that I can call its functions anytime and also save persistent variables and that also initializes before actors. Now I created a blueprint, BP_WorldSubsystem and it works perfectly as needed. Now I created another blueprint class of my world subsystem, but I cannot seem to find it in the blueprint graph. The image shows that I can actually bring the BP world subsystem anytime but not my new BP Mission Manager. Does anyone knows what might be the issue. I have added the new blueprint class to my defaultengine.ini file. Is there something I am missing?
