delete scale

[CAROLINA]

I can't understand...... because I can't cancel this scale anymore.... .

when the seleziono is like the software was locked doesn't even let me access the modification of the scale..... .
someone can tell me what could happen and how to unlock it all thanks and a thousand...... .

Did you block her? Can you select it? If yes, near the ladder is a pin?
