Cannot turn to second page

Hey, Thanks for this plugin.

I have 139 files to download and wanted to display them on pages that show each 50 files.
But if I click on the page menu (1, 2, 3, 4) on page 2, it always loads the first page, but never the following.

Is this a bug?

(I solved it for now by displaying all the files on one page, but I was wondering, if this is a bug)

Best,

Lisa
