Material Billboard - SetMembers not working in runtime

Greetings,

I have encountered an issue with Set members in MaterialSpriteElement when trying to modify the values of any element of a Material Billboard Component.

In this example, I am just trying to modify the size of the element at index 0; If I do it with Set members in…, it doesn’t work, but if I make a new array of elements and set this new arrays to the material billboard component, it does; this workaround is what set members in conceptually does (I think).

I don’t know if this is a bug or I have the wrong understanding of what set members in does. Let me know if you need any additional input from me.

[I included the project with the 3 functions depicted below, just change the function being called OnBeginPlay and hit play, you’ll see the square change size if the proper function is being called.][2]
