Turbo-portland theme, Items stop at 48 or 50 even though there is 250+ in a collection

[sageandwillow]

Hey all, I'm trying to figure out how to correct my theme.  I have 2 fairly large collections that seem to stop at either 48 or 50 pieces even though I've got infinite scroll on.  I'm not familiar with my own coding but seeing if I'm missing a step along the way.  My "All" collections seem to work just fine, but some of these other collections stop at the 50 mark and won't automatically scroll down.  Any help is appreciated.
