Trigger setup menu opens old settings

Hello, we have noticed since switching over to using admin center that when you are configuring a trigger it will sometimes open in the old window with the orange side bar, inside of the current admin center window. 

I have done a few tests and have noticed that on our instance you can either start a to configure a new trigger and then click cancel and when you go to add a new one it will load the other menu... or if you just add two new ones in a row.

I have not noticed any change in how things are saved or work so i don't assume this is anything high priority just wanted to mention it. 

I have a screen recording if you need you but it doesn't look like I can attach here.

 

Thanks, 

Meg
