As per manual, try to find a combination of attributes that works.
For example, if there is a single 'submit' button or text on the screen, you can only leave 'Value' ticked as an attributes in Application Modeler.
Please note that this can make the element longer to identify and therefore it is best to have multiple attributes ticked.
As per good advice above, do use timers if moving from screen to screen of the application.
Finally, make sure you are connected to the application and there are no 'dual matching' happening.
