Steps to reproduce:

1. Logged in Liferay, go to Site's Configuration > Application Display Template;
2. Add any type of ADT;
3. Click on Export/Import in ADT's home page;
4. In Content fieldset, click on Refresh Count;

Expected result:
The checkbox of Contents should be able to be checked or unchecked as it was before the Refresh Count action.

Actual result:
The checkbox of Contents is unchecked and disabled. That way no ADT is exported when you try to continue the exportation.
