A phenotype can appear as both positive and negative in the "Current selection" in certain conditions

Steps to reproduce:

• Open or create a patient record and go to the "Clinical symptoms..." section

• In the "Quick phenotype search" box type a query, e.g. 'fever'

• Select

  [N]

  for Fever

  • Result: "

    NO Fever

    " appears in the Current selection panel

• In the quick search box type 'fever' again

• Select [Y] for Fever

  • Result: "Fever" appears in the Current selection panel *in addition to "

    NO Fever

    "

The expected behavior is: "Fever" replaces "NO Fever".
