I reached Apex Predator in arena shortly after season 10 launch (08.08.2021) (see attached screenshot pred.png)
However I only have the Masters arena badge unlocked with the launch of season 11 (see attached screenshot master.png)

According the the initial announcement of ranked arenas https://www.ea.com/games/apex-legends/news/arenas-ranked
And this twitter post by RSPN_JayBiebs https://twitter.com/RSPN_JayBiebs/status/1423077766455435264
The predator rewards should be unlocked even if you do not maintain predator rank throughout the season.
