Flow control question. Two inputs for one UMG action problem!

I am working on archviz project and now I am busy with UMG part of it.

I got stuck on flow control part. I have a main menu which is visible when I press Tab, pressed - up, pressed - down. On this menu I have variety of buttons. When I left click on the button, the main menu should go down, but when I press Tab again to have this menu back, I need to click two times. it look like when I press Tab again the system doesn’t know that Main menu is down and pull it down and only on second click it will bring it up. How can I resolve this issue?

here is video and pic of my BP.

Thanks in advance.
