Why did my matches not count towards the Cybertruck challenge in Rocket League?

To complete Challenge #3 (available from July 31st, 2024, and August 6th, 2024) and earn the Cybertruck gear, you needed to meet the following requirements:

• Play 5 Online Matches in a party.
• Have the Beast Mode Boost equipped.

Meeting only one requirement was not enough to unlock the Cybertruck gear.
