All texts on signs disappeared

In this new version, every single texts I wrote on my signs disappeared, I tried joining a world I downloaded from an app, and the world was created before this version, there's still nothing on the signs, and I'm so confused on some games that have instructions that I can't read because of this glitch, this Pic had texts in it before this version and they and every single text in every world disappeared, please fix this it's so confusing and annoying
