Can not delete edge data in Vertex after drop edge class at ORIENTDB

1. Table A , Table Bをvertexとしてあります。
2. Table A , Table Bを繋ぐJoinというedgeを作成しました。
3. そして”drop class Join”でedge classを消しました。

テストの為に上記の2.と3.を何回が繰り返しました。

すると次のようにin_Joinに無駄なデータが一杯出来ました。

SELECT FROM Table where name='Table A'








その後に"delete edge"をしたらエラーが出てvertex上にあるedge情報が削除出来ません。

orientdb {db=TestDB}> delete edge join from ( SELECT FROM Table WHERE name='Table A') to (SELECT FROM Table WHERE name='Table B')

2016-07-05 14:40:10:304 WARNI {db=TestDB} Record (#40:0) is null [OrientEdgeIterator]
2016-07-05 14:40:10:304 WARNI {db=TestDB} Record (#37:1) is null [OrientEdgeIterator]
2016-07-05 14:40:10:305 WARNI {db=TestDB} Record (#37:0) is null [OrientEdgeIterator]
2016-07-05 14:40:10:305 WARNI {db=TestDB} Record (#38:0) is null [OrientEdgeIterator]
2016-07-05 14:40:10:305 WARNI {db=TestDB} Record (#39:0) is null [OrientEdgeIterator]

これを削除するためには
 update #23:0 remove in_Join=#40:0
を実行して１つずつ消すしかなさそうです。

------------
Draft below here

There are Table A , Table B as vertex.
I create edge as Join that connet Table A and Table B.

And I drop Join edge.
