Hello/Hi/Greetings,

I am trying to create a batch download of 195 ~5-10Mb images from a collection.  When i click download, it goes to the generate page, and says that the size is 0 and the number of archives is zero and it does nothing else.

If i select XXL images, it processes them and creates the zip files.

any help on fixing this would be great, thanks.
