size problem of editbox in layout grid with breakpoint

[avent]

Hi,
for learning, I have done a simple html page from scratch with one layout grid with 3 column, 2 empty while in the central one a simple contact form with text, horizontal line, editbox, textarea, button and font awesome icon. I set 2 breakpoint (480 and 320).
In default size all is OK but into breakpoints all element except text become small in proportion of the size of breakpoint so they are too small.

How can I do to mantain the right size?

I'm sure that the solution is simple but I don't know it

Can someone help me?

Thanks

Maybe you have enabled 'Automatically scale new objects in breakpoints' in Tools->Options->General?

Yes it was enabled,
I've disabled it now and then, also the old component inserted are not affected by the change, the new inserted mantain a right size and work fine.

Problem Solved.

Thanks
