ACF and visibility conditions

I temporary fixed the issue.
I set the following condion:

and the result is ok:

The field “Exclusivité” is a toggle “No/Yes” so the default value is “No”.
If the target value is “No” and the user doesn’t click → all is ok
But if the user clicks “Yes” then “No” → the settings becomes wrong because “Exclusivity” becomes “not empty” but with value “false” (0?) and the display is not the expected one.

I really want that my setting runs according to the value “True” or “False”.
But with the present behavior, we seem to be in Quantic Physic where the value of “Exclusivité” seems to be in the same time “True” and “False” (see previous post).
