I'm kind of new to Blender, so this might be a really easy question to solve - I just couldn't find anything on the internet so far.
I created a particle system and already changed the settings to how I wanted them to be. Now I want to change the lifetime of the particles (make it longer) but I can't figure out how. When I try to do it how I did it the first time, it doesn't work because the setting panel seems to be 'blocked' or so (see picture).
When I select the Particle Setting specifically, Blender tells me that it is not yet implemented.
