Incorrect users displayed on my own favorited observations

Please fill out the following sections to the best of your ability, it will help us investigate bugs if we have this information at the outset. Screenshots are especially helpful, so please provide those if you can.

Platform (Android, iOS, Website): iOS

App version number, if a mobile app issue (shown under Settings or About): 3.3.2

Screenshots of what you are seeing (instructions for taking a screenshot on computers and mobile devices: https://www.take-a-screenshot.org/):



Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):

The 1st screenshot shows what it looks like before I favorite the observation. When I favorite an observation of mine that someone else has favorited, it says multiple of one user favorited it. Sometimes they haven’t favorited the observation in the first place, as seen in the 3rd screenshot. The website still displays it correctly. This happens on multiple of my observations, not just this one. This does not apply to observations from other users

Step 1: Open iOS app

Step 2: Go to one of your own observations that someone else has favorited

Step 3: Click “Add to favorites” and watch it load, then display the people who had favorited it
