All is in the title.
To correct this problem, i modify the "repeat_elements" function.
When the function clone the differents elements, i copy all of them in an array.
When the function applies the differents options for the cloned elements, in the case of a 'disabledif' option, i compare the name of the conditon of the element with the array. If it's in it, i change the name of the condition with the nice bracket [no].
It seems to work fine.
