Moved Intensity column in spreadsheet 1.2.1 b550

Hog4 ver 1.2.1 (b 550) and Hog4 PC(same ver)

We could move the spreadsheet column within the editor.
However, once Intensity column to most left side.
You can't move Intensity column any more.
This happened any editor windows. (Programmer, cue editor)

This doesn't happen with any other parameters.

Thanks,
Aki
