Wandering trader spawns more than one time per world

I just had two wandering traders spawn in my world but it is bedrock 1.12.1

Just had two spawn on my single player world. Created with Java version 1.15.1 and currently running 1.15.2

This should not be fixed or altered, because fixing this bug would mean significantly reducing wandering trader spawns. With the current spawning chance, it takes almost 5 hours for a wandering trader to spawn. This means that on servers with a large amount of players, the odds of ever seeing a wandering trader are already extremely low. This would lower the chance even further, by requiring players to wait 48 THOUSAND ticks (40 minutes) before the spawning algorithm to continue. Players in singleplayer who aren't interested in the wandering trader are free to use the doTraderSpawning gamerule 

This is still present in 1.15.2
Have just had 2 wandering traders spawn within a couple of minutes of each other in the same village.

Can confirm in 20w51a.

I think this just happened to me in 21w19a. I have 2 wandering traders within 3 or so chunks of each other.

yesterday i had 4 wandering traders on a desert,no idea how they got there
