The link to find all Add release edits by editor is missing edit type 216 (probably legacy Add release edit type):
Should be replaced by:
&conditions.1.args=216%2C31 where %2C is a comma (,).
This problem also apparently bugs the amount that is displayed.
Maybe for the same reason, this editor shows 0 added releases despite having in fact 24 added releases if we search with two types 31 (most recent Add release type) and 216 (probably the legacy Add release edit type).
