Hi @ryneboi, welcome to the iNat Forum. Screenshots and URLs are helpful to explain issues you are running into.
If you are making identifications, I’d highly recommend using the Identify page instead: https://www.inaturalist.org/observations/identify?taxon_id=49470 (quick tutorial here)
Collection projects like the one you mention have only ever shown the latest couple hundred observations. If you click “View all” or “Search” you can view all the observations in a project.
Or if you just want to see springtail observations just start typing in springtails in the main website search and click “View observations”:
