No. It is a problem with her advisor and the other mentors she has had at her school. Professors (and senior graduate students) should be teaching students that you are learning many things as part of your Ph.D. training: How to do research on a problem of interest, how to find a problem of interest, how to write a paper backing up your research findings, how to give a presentation of your research findings. These are all important. But they aren't the end.
You also need to be learning: How to explain your research to experts in your subject (department), how to explain your research to others in your discipline (college) [ We called this the "elevator talk" ], how to explain your research to those without a complete background (other graduate students), how to explain your research to students majoring in your department, how to explain your research to john q. public [ We called this the "airplane talk" ]. How to find funding and how to make a report on the results from funding.
