pgr_withPointsDD return wrong cost when details:=false

[apslight]

QUERY

'SELECT id, source, target, cost, reverse_cost FROM edge_table ORDER BY id',
'SELECT pid, edge_id, fraction, side from pointsOfInterest',
-1, 3.8, driving_side := 'b', details := false);

Driving distance starting from point -1 which is the little house one the left side of edge 1 and only for 3.8 units far away.

Output (when details:=false)

seq	node	edge	cost	agg_cost
1	-1	-1	0	0
2	1	1	0.4	0.4
3	2	1	0.6	0.6
4	5	4	0.3	1.6
5	6	8	1	2.6
6	8	7	1	2.6

details:=false which ignores other points of the points_sql.
Actual Behaviour : in 4th row the cost of travelling edge 4 is 0.3
Expected behaviour: But instead of 0.3 it should be 1 which is actual cost of travelling of edge 4.

when details:=true then it is coming correct.

Can you also post the results when details := true just to have the comparison at sight
