https://xalgo-system.herokuapp.com is not saving any data above the decision table

[jpotvin]

Data within the decision table and below it is being saved, but all data above, other than Name & Description, is NOT being saved.

Upon clicking the Save icon, there does appear:
A yellow messagbox: Warning: Rule did not pass schema checks.
A white messagbox: Content UUID c44dfa80-dac0-449b-b81c-4cd4394e841e was saved successfully.

But the content that I had just finished entering into fields like ISIC and UNSPSC is gone.
