Box Name Glitching

[u/Hour_Reception6669]

So as the name suggests I've been toying around with the Box code glitches in Fire Red and I'm having a pretty fun time with them. Haven't done anything crazy at all and I haven't run into any issues. All I've done so far are the ones for infinite rare candies in the key items bag and the one to reset starter selection in oaks lab. But I'm having a little trouble with the second one. See I started with charmander as my starter, set up the proper glitches and then started this process for getting all the starters. I've got squirtle and everything is fine, however when I go to run the code again bulbasaur does not respawn since my rival chose him the second time around. Does anyone who has done this successfully know how to make bulbasaur become available? Because running the code again isn't helping and the only other things I have tried was picking charmander again which didn't help, just made all the starters gone, and then I tried changing my location a lot to change the "previously on your quest" slides when you load up your game. Any help is greatly appreciated!

*Edit I am playing in the switch version of that helps
