Pagination returns wrong number of collections

[satzomatic]

Hi all,

I'm showing all our collections on the homepage and paginating them with {% paginate collections by 20 %}

However, this only returns 19 collections on the first paginated page, even though it correctly shows 20 on the subsequent page.

If I set it to anything below 16 collections, it works correctly – ie. 16 collections are shown on each page, but setting it to 17 and above always shows one less collection on the first page.

Any clues appreciated!

Thanks

Michael
