Japanese crruption using table editor.

I'm using DraftSight 2015 SP3 Professional(30 Days trial) with Windows7 Ultimate x86.

I tried to add my 'User definition standard' editing Table Editor. In Japanese install,the characters in that table editor are corrupt, so I cannot understand what are written at last row.

And I cannot add materials contiguously.

It's only way to add something I could was edit a cell, save, open again, edit a cell, save, open again, edit a cell and forever.

Does anyone else have some solution about this problem?

Thanks.
