Hm, unfortunately I think this made it worse. Now when I hit the add more within that small group the parent group gets added.

So this is what I want it to look like if possible:

Date
Title
Description
Video Location
Additional Features [
    File Name
    location
    image
    [add more]
    File Name
    location
    image
    [add more]
    File Name
    location
    image
    [add more]
]
[add more]

But this is now whats happening after I press the plus button

Date
Title
Description
Video Location
Additional Features [
    File Name
    location
    image
    [add more]

        [add more]
    ]
    [add more]

[add more]

Is there something special I need to take into consideration for groups within groups?

Great! I just sent the email!
