Multiple blogs Category filtering

I'm trying to get multiple blogs working on my site for the first time. The blogs will be 'blog' and 'resources'.

On my index pages I'm doing some filtering for that blog's posts using 'blog' => 'resources', which works fine in the perch_blog_custom array.

Passing the same thing into my categories works ok with the 'blog' blog but not with 'resources' blog…

This works fine:

perch_blog_categories([
  'sort' => 'catTitle',
  'sort-order' => 'ASC',
  'blog' => 'blog',
]);

But this doesn't return anything:

perch_blog_categories([
  'sort' => 'catTitle',
  'sort-order' => 'ASC',
  'blog' => 'resources',
]);

Do you know what I might be doing wrong?

Incidentally, it works fine with perch_blog_date_archive_years and perch_blog_tags.

This is my debug code:
