Edit Response doesn't always allow Pole plusError and minusError to be/remain deleted

[metempleton]

I created three BH channels using the Network wizard and NRL. I edited all four pole values and deleted plusError and minusError for Real and Imaginary parts and saved the results. When I reopened the poles, 2 of 4 had the Errors once again (and every time
I tried to delete them after that). Since the Error values are incorrect, I really want to delete them.
