Description

For relations (between tables) feature, it is important to have unique values in column (referenced field), which is used as a foreign key to the second table. It would be nice for plugin to detect, if this values are not unique and inform the user, it will not works well in INPUT.
INPUT in case of multiple values chooses one of them.

Research direction

Start by reviewing the plugin's relations feature and the INPUT behavior when a referenced field has multiple matching values. Reproduce a relation with duplicate referenced values and trace where the plugin can validate or report it. Done means users are informed when the referenced field is not unique and the problematic INPUT behavior is covered.
