Cannot find project on iPhone

#1

My latest three projects are not appearing in the list of projects to join on my iPhone.

It might have something to do with having 184 projects joined. Other people around me have no such problems.
The project is https://www.inaturalist.org/projects/cape-town-school-nature-challenge
My projects are: https://www.inaturalist.org/projects/user/tonyrebelo
am using 2.7.17 build 522 on my iPhone.
