More context would make it easier to assess the training. Trianing age, which macro/micro this is in, etc. There are numerous factors which could impact training, and without seeing the full body it would be speculation. However, traditionally you would see the days broken into am/pm sessions to support the specific theme.
Open dialogue with the coach fro mthe athlete expressing concerns would be best. He/she may be willing to go through the annual plan with her. based on her marks she has a vast amount of potential in the heptathlon. Best of luck!
