Fixture Definition Editor - Edit channel Capabilities bug / feature

[bosko1333]

Greetings!

I made a mistake during capabilities listing and I tried to insert some values between existing ones. There is no option to do that. I tried to add it at the end (with correct number) and even that did not put them in.
Is there any possibility to add this option into the definition editor?

Also, when I select row to delete with red minus icon, sometimes it deletes one row above.

Thank you!

Version?
Please add your definition attached.
You cannot insert values if the upper value already is 255 - first, make some room and then insert.
