Not appearing ASCII Code

The Version i´m working with 3.0.6 (v3.0.6-0-g908c8e357d0f).
The ASCII Code is not appearing in the Package Bytes menu. But if i switch the zoom option to smaller it is appearing, so its a Bug in the Zoom Option.

You can send me a mail to [email protected]
it would be a pleasure if i will be notified by you.
