Why does the profile width parameter of Line Profile (Image menu) not work properly for small-step-value images?

I am using the Line profile function to analyze an 2D image spectrum. It is found that the profile width parameter doesn't function properly, which only works for numbers larger than 1, or only updates when the profile width increases by integer numbers.
For example, the X coordinate of my 2D image starts from 0 with a step of 10E-9 (nanosecond) for 5000 points (picture below). I changed the profile width to integrate an stripe area. But the profile never updated, but always showed the profile with 0 width.
Furthermore, another problem is that I can not directly type numbers in the profile center and profile width, when the numbers are smaller than 1. I have to use the up/down increasement buttons to change the value.
Above problems happen on both IgorPro7 and 8. The operation system of my laptop is windows 10 with the latest update.
