Not possible to save subtitle of journal issue

[kleinann]

Trying to save the subtitel of the following bibliographic resource, it always vanishes:
Abelshauser, Werner: Die Wirtschaft des deutschen Kaiserreichs ein Treibhaus nachindustrieller Institutionen in: JOURNAL_ISSUE Windolf, Paul (ed.), Finanzmarkt-Kapitalismus, Kölner Zeitschrift für Soziologie und Sozialpsychologie Sonderhefte, Vol. 45, VS, Verl. für Sozialwiss., pp. 172-195.

@chah3d can you check it? The subtitle vanished after clicking submit; it happens for the JOURNAL_ISSUE only. For the other resources, it works well.

Some time ago (~ before our 2nd workshop) I noted that the subtitle field was simply missing in our data model for some data type. I do not remember exactly which datatype it was though. I told Anne and she fixed it quickly.

So either (a) these back-end changes did not make it into production yet or (b) it is the same problem but for a different data type.
