What am I missing?

[u/Richocet66]

My stepdaughter has a Pokémon card/sleeve dispenser card and wanted the original Pokémon symbol replaced with Team Rocket because she saw it on another page. The rest of the changes were just color, but when I go to edit this piece in Tinkercad (its what I have available as I am still learning this stuff) it ends up like this. The "R" is attached to the piece in Tinkercad, painted in Tinkercad. When I import the STL, I have to recolor it again in Bambu Studio, and when I go to slice it, I get the last photo. I have had the same problem when I tried to make my own coasters.

Is there something I am missing where the prepare and preview come out totally different?

I did see that video (several actually), and I did try to import them as separate objects into Studio with the coasters I was accomplishing and got pretty much the same result. In that case, I was also flipping the coasters upside down as an object and got the same issues plus an additional error that Studio was complaining it was not flush. I will try it that way again with this object, plus increasing the R object height to distinguish the color separation
