If play 4th suit double,I should make double instead of 2♥ here.
Now I strongly suggest Gib should play 4th suit double.
The basic meanings :
1- Pass = weakish hand
2- double = promises 5-card ♥ with ♦ support.
3- raising to 2♦ = deny 5-card ♥ .
4- bidding 2♥ = 5-card ♥ without ♦ support.

Any idea?

Isn't West hand just a double?

I agree that dbl should show five hearts, this is called a snapdragon double and is completely standard.

With 4-card support you can bid 3♥, though, or maybe 2nt if you think that 3♥ is too rich and trust that partner can understand that 2NT by a passed hand can only be this hand.

If you were not a passed hand it is not so obvious what 3♥ and 2nt would mean.

For this convention is normal to play double as ♥ and ♦ tolerance. This is called by some Snapdragon.

With a hand like yours it is very strong for a passed hand. By a passed hand some people play fit jumps so 3♥ would be 5♥ with a good fit for ♦.

Good luck getting a new convention BBO doesn't regularly add things, they have enough to do fixing things.
