Bug in display Allow custom value in tag of new table

Say I have a demo table

by default the tag in Role column is disable in Allow cusom value,
but when I click to edit option list, it was checked.

Then I click Mapped and select javascript array as datasource

The checked was unchecked automatically.

Then I checked the Allow custom value

And the allow custom value work
