constructor row constraint is not applied to all rows

We recently updated from an old version to 11.0.
Now we have the issue that a row constraint `AC().gap("0") ` given as a constructor parameter is only affecting the first row gap, but for subsequent rows the default gap is applied.
We found a workaround with `LC().setGridGapY("0") ` but i think this is still a bug as the constraint should be applied to all rows.
