Describe the bug

Given you have a popup with an Auto Open and Click Open trigger.

The Time Delay Settings > General shows a blank tab (error) when you edit Click Trigger Settings > Advanced immediately before editing Time Delay Settings.

That's because PM is probably remembering the last tab I was on was the Advanced settings for the Click Open trigger. So it tries to open or display the "advanced" settings for my Auto Open trigger, but there are no "advanced" settings for Auto Open triggers.

Expected behavior

The Time Delay Settings > General settings should display instead of showing a blank tab.

Current behavior

The Time Delay Settings > General tab is blank because PM is probably remembering the last tab I was on was the Advanced settings for the Click Open trigger.
