Trivial poles and zeros displayed as 0+1j in cell in P/Z tab

If I design an FIR filter all its poles are 0, and are shown properly in the P/Z diagram. However, on the tab where you can edit poles and zeros they are displayed as 0+1j.

Editing a pole and setting it to 0 will result in it being displayed as 0+1j in its cell, though it will still be treated correctly as 0 everywhere else. The same goes for zeros: setting the cell for a zero to 0 will result in it being displayed as 0+1j in its cell, though the zero on the P/Z diagram is correctly on the origin.

This is for version 0.7.1.
