The first,I should pass with only 4 hcp.
then the second,after double,Gib N should rebid 1nt instead of 1♠,this is a GIB rebidding descriptive wrong.
How are there different between 1♠ and 1nt?
the meanings of rebidding 1♠ showed 5-4 or 4-4 distribution at least with low limited values, and usually it is a unbalanced hand.
the meanings of rebidding 1nt showed 18-19 hcp with balance,maybe have any 4 card major.
I think this is a basic bidding principle,what else?

Thanks for reporting.

Fixed for such balanced and strength corresponding to 1NT rebid ( 18,19 ) to bid it instead.

There was also bug preventing 1M to "see" the rebid 1NT over 4th seat balancing double. 5332 shape.

Sorry,I don't believe it can be fixed completely,Gib play up the line as a basic principle not walsh , so actually this is the ills of such bidding style.

GIB would rebid 1NT over 4th seat double with any hand that would rebid 2NT ( 18-19 ) over partner's bid in uncontested auction if that describes better.

Would bid other suit or something else only with unbalanced hands.
