It is controlled by size, but it's a per list attribute.

The paginating of the member list is controlled by the list attribute
admin_member_chunksize which is set at list creation time from the
Defaults.py/mm_cfg.py variable DEFAULT_ADMIN_MEMBER_CHUNKSIZE (default
value = 30).

The problem is admin_member_chunksize is not available in the list
admin GUI or in config_list so once a list is created, you have no
easy, visible way to change it. See

In your case, it appears that DEFAULT_ADMIN_MEMBER_CHUNKSIZE has been
changed so older, pre-change lists have one value for
admin_member_chunksize and newer lists have another. You can use
bin/withlist to change it for an existing list. For example - set
admin_member_chunksize = 100 for the mailman list

$ bin/withlist -l mailman
Loading list mailman (locked)
The variable `m' is the mailman MailList instance
>>> m.admin_member_chunksize = 100
>>> m.Save()
Unlocking (but not saving) list: mailman

The '>>>' are Python prompts - the 'empty response is a control-D
