"Manage Activity" or "Manage Volunteer"?

I stumbled upon a problem for copy writing, whether to display the copy write as "Manage Activities" or "Manage Volunteers". These two choices is supposed to be the replacement text in the pictures below with the blue box. In order to decide, here are the 2 pictures of where to put them:

First, Sorry for non-english content but I will try to explain. I have this "Pipeline Aktivitas" in the dasboard home. This section displays 5 activities of an organization. It shows the registered volunteer status in the certain activity. For example, in the "Workshop Online: Recycling 101 bersama Kertabumi" activity, there are 0 Baru Daftar (Application), 33 Perlu Briefing (Admitted), 0 Aktif Bekerja (Active), and 82 Selesai Bekerja (Finished).

Second, Again, sorry for the non-english content. In this second picture, it's the same as above but the page only shows one certain activity, not a list of it. It basically shows the same thing but with thorough information of the volunteers.

Now back to the question: Should I put the title as "Manage Activities" or "Manage Volunteers"? My concern is that the title is confusing for users.
