Conditional logic in html field does not work anymore

As title,
my conditional logic to show an image for example, does not work anymore.
The former conditional logic (in the same form) still works but the new one not.

Yes sure.

Now i removed the imgages because it always show them even if the conditional logic is not verified. To be clear it seems that right in the back end while i'm editing the form it does not mantain the conditional logic.
But not always. I tried with a new form and it works.

Thank you

Ok,
i have a complex form with multi option for a print. This work perfectly but to make it nicer i would like to add the right image corresponding to the right paper choice. So when you choose for example "photo rag" it will show you a photo of the photorag. This is pretty obvious to do with a conditional logic and an html field with the image embedding code. But the logic does not works.
Furthermore, in the same form there is an option for choosing the mounting panel that uses the same concept to show you an image the right mounting panel, and this works perfectly.
What i'm dealing now is the fact that the option of the html field do not save the settings when i click the save (update) button.
Is there some limit in dimension in gravity form?

Understood something.
In the drop down i have several value based on the paper choice. Some value are the same. So the conditional is based on the value and not on the label name! Is there a way to change that?
