Don’t copy and paste the precomps from within the comp, you are just making an exact duplicate—just like if you copied/pasted a video layer within your comp—it’s just a duplicate linked back to a single source.
Find the precomp containing the text in the project window and “cntl+d” to make a duplicate of it(at this point I would rename that duplicate). Now drag that into your final composition, and you can open it up and make the text changes you need.
