The installer automatically creates a backup. Take that 'old' baseitems.2da and overwrite the new one. Then add the new rows.

But the duplisaber baseitems.2da is not provided with the mod because the installer does the work to create or alter one. You may contact VarsityPuppet for that. I won't upload the one he gave me cause it's not mine.

As far as I know it's a problem with the installer. The defect baseitems.2da causes the white boxes and missing items. So I don't think making a clear install will work. (I may be wrong)

The author provided me a clear .2da and I copied the new rows. Voila, it works perfectly.
