Struggling with After Effects Callouts

Hiya, I am new to the forum and After Effects. I have downloaded a callouts box, when I duplicate it and change text, it changes across all the callout boxes in the scene. I have tried to follow online instructions about duplicating in the project panel. but it still does this same thing, please may i grab some advice, absolute newbie, at point of tears after trying to hours , thank you

It’s impossible to offer help on your case, although there may be some content/guides on Google ( You could search ) but the most appropriate way should be “freelance/paid” support.

If you’re not interested in, it’s something that you’d need to “expertise” and solve on your own..
