After 1nt,Gib N rebid 2♣ as nmf with 4 card ♠,and then pass my 2♠,I think it should rebid 2nt as invitation.I am wondering why rebid 2♣.

I'd prefer North to pass 1NT and not invite with 10HCP (yes, plus three tens) opposite a max of 14HCP. I expect that North is counting his hand as 11 total points, including one for a heart doubleton, so he feels the need to invite.

The explanation of 2S is truncated. Does it also show a minimum 1N rebid in addition to the delayed 3 card Spade support? That might explain why North felt that there was no profit in moving further.

It is a known bug with the hand presentation software. It has been around for a long time and there is no known fix nor apparently any prospect for correcting it.

I think that it only happens with the explanation of bids ranked on the far right of the diagram, normally South.

Yes, that's exactly what it shows.

It has been fixed previously for

1m - 1M
1N - 2om

Fixed in next version and for 1♥ - 1♠.

So
- with INV values and 5+♠ GIB would use NMF
- with GF values and 4+♠ GIB would use NMF
- with INV but bal 4th♠, GIB would invite directly ( 11-12HCP )

otherwise ( like here in example ) GIB would pass.
