Text in some parts is just vanishing

Hey, I am using Textmeshpro UGUI in several parts of my projects for my game on iOS, however, as soon as I finish building and loading it on the iPhone some text are just gone. I am not using different Text components or shaders/materials for the texts. I have also tried replacing the texts with texts that are functional in other parts but suddenly do not work anymore.

Everything works fine in the playmode. What could be the reason?

I figured it out, Textmeshpro had issues getting the strings from a large concatenate function
