Filter of lessons does not reset when student is added

[nus-pe-bot]

Steps to reproduce:

1. filter g/p2 - All P2 Students and Lessons shown
2. add n/Tom p/98765432 e/gmail@gmail.com a/123 g/p2 - Adds a P2 Student, Students' list filter is reset but not lesson list's filter

Expected: Lessons' list should be reset as well when student list's filter is reset.

Team's Response

we designed our app to only refresh one list depending on what entity (student or lesson) is being added. Hence we feel your concern is more of a feature flaw rather than a functionality bug. We decided to change the severity to low, as in our consideration, we think that it is a rare occurrence that our target user would want both the relevant panels to change when adding either entity.
