What is the Opening bid meaning of 4NT?
I thought it is blackwood and ace asking and GIB passed it.

I think the most common (least uncommon) meaning of a 4NT opening is to ask for specific Ace, if any.
GIB doesn't have that agreement and so treats it as natural NF.

what did the bidding box say when you hover over it before you bid it, if it isn't close
to what you expect it to be don't do it.

No description. It is blank. Now I guess it is to play.

it would seem that it should have a meaning doesn't opening 3NT show some wicked high range?
I guess then if you hover and no explanation you are in unexplored GIB territory
