Sorry to her this has happened, due to how the search grid works this can happen on rare occasions in an update but is very very easy to correct.
on the patient search screen if you right mouse click anywhere on the headers shown on the grid and choose "table properties..." you will see a button labelled "Reset" in the lower left, click this then click "Reset All".
this will allow the grid to realign the fields and all will be back to normal.
