We are validating Apex 18.2. The App is Working well on 5.1.3.
When we try to Open the Popup to show Values, it appears hidded, behind the main screen. It does not even open a New Tab on the Browser

This is Working the version . Working Well on APEX 5.1.3.

This is The one not Working, APEX 18.2. Not opening a new Tab, just hidded behind the main Screen.
Any Ideas what we can do to Solve this ?
