UI Bug - Cannot Save EventLab Favorites

Bug Info: If I try to save an EventLab favorite from search results and then switch to the Favorites tab, the favorited events are missing from that tab.
Platform: Windows PC
Edition: Premium
Account: Solo account
PC GPU: NVIDIA GeForce RTX 4070 (Driver version 561.09)
Peripheral: Turtle Beach Recon Xbox-style controller
Settings: 2560x1440, nearly all optimal settings recommended by GeForce Experience, but VSync is on, Reflex is off, and RTX: DLSS is off (my monitor only supports 60 fps).
Xbox Settings: N/A
Attempted fixes: No Support ticket was opened. I noticed the bug in the past few days, and came back to the game after starting up my computer again today to reproduce it, so I guess that counts as a reboot. Reinstallation not attempted. Default settings not attempted. Rolling back drivers not attempted.
Content Update: I only noticed this bug on the current version of the game (Build 660.281, Data 38,000). If I remember correctly, my favorites were accessible in a prior version of the game.

Steps to reproduce:

  1. Open EventLab Creations (Browse Events).

  2. Search for anything on EventLab (I searched for events on EventLab Island containing “miniracers” in the name).

  3. Wait for search results to appear.

  4. Add some events from the search results to your favorites.

  5. Switch to the Favorites tab.
    Expected behavior: Switching to the favorites tab should show these events.
    Actual behavior: Switching to the favorites tab does not show these events.

  6. Switch back to the Search Results tab.
    Additional behavior: Switching back to the search results tab causes the favorite tags to disappear from the event cards.
