Interferences between Dataset Templates and controlled vocabularies added to citation.tsv?

Version: 4.20

Zdravo,

We think there might intereferences between dataset templates and controlled vocabularies.

We tried to add a controlled vocabulary for the Topic Classification > Term field (based on the CESSDA Topic Classification) by modifying the citation.tsv file.

Everything seemed to work fine when we got to the Add Data > New Dataset form: the field had become a dropdown menu and the input values could be selected.

But then, after saving the changes, the field was empty in the metadata:

(And the content of the Vocabulary URL field also appears between quotation marks.)

Interestingly, if we add more instances of Topic Classification by clicking the + button, the value put in those new instances are saved, but never the first one.

We tried creating a new dataset but this time without any dataset template (we have one selected by default). Then the information was properly saved in the dataset's metadata.

I should also specify that, in our templates (all of them), the Topic Classification > Vocabulary and Topic Classification > Vocabulary URL are prepopulated, but not the case of the Topic Classification > Term field:

(There is also a custom watermark as you can see, but we added it only after observing the problem.)

We could perhaps try to replicate this issue on Demo Dataverse?

Start by reproducing the problem in Add Data > New Dataset with a dataset template and the controlled vocabulary from citation.tsv. Compare the first Topic Classification instance with instances added using the + button, including the Vocabulary URL value. Done means the initial Term and Vocabulary URL values are saved correctly when a template is selected.
