Button unclickable after setting it to visible

[Helkios]

Hello, I seem to have a small issue, I have a button in my UI that sets the visibility to another part of my UI to true, inside that other parts I have other buttons, but they do not work when I click, If I set visibility to true from the start then they work.

blueprint that makes that part visible:

Here is what it looks like ingame, the + && - buttons simply do not work:

I thought it might of been a focus issue but even when setting the focus of these button to true, nothing changed and at this point I’am at a loss. anyone facing similar issue? is it a unreal 4.15 issue?

I think I found the problem, it is a focus problem when I set the visibility to true I need to also set the visibility of my other buttons to “Set Hit Test invisible” this apparently fixed it.
