Thank you Stwert & edgewalker...

I discovered that if I used the scale tool manipulator before I modify segments, I get these issues.
But if I scale using the channel editor, then theres no issues.

So, this is my question:
When I scale an object using scale manipulator (hotkey R), should the scale value show up in the channelbox?
Mine does not show. Is that normal?

Thank you.
