Double-click icon in sketch doesn't work.

[PAPAMAO]

I know double-click icon in catia sketch can repeat command.
Recently, this function works if I draw profiles like lines, circles….. after double-click icon.
This functions doesn’t works if I constrain profiles like lines, circles….
For example constrain lines. After double-click icon, first line can be constrained.
But when I constrain second line it cannot be constrained. It works if I have constrain second line again.
How to solve this problem?

Thanks.
