print from users input linked list of struct

I am required to have a list of structs of sentence nodes that point to a struct of word nodes. I am trying to print the user's input.

I have a program that runs properly when I manually give it the input (see test section of the code). It does not, however, work when I use my input1() function.

I've tried debugging it, but I can't seem to find the problem. I removed all printf lines that I used to debug. I also removed all the irrelevant code.

I am looking to know how to fix it and what is wrong so I can run it with no problems.

What I learned from debugging it is that (only when using input1() and not in the test) the head is overwritten every time and all the nodes as well. I also tried using a double pointer instead of returning para but that didn't help.

any help will be appreciated,

thanks in advance
