I’m unfortunately not familiar directly with the Univention Virtual Device, however, the first place that I’d look is in the config.php file that stipulates a range of currencies. I’m going to cut and paste the whole of the currency bit from one of my systems, so sorry for the length:

Check that those entries exist, and if not we can start looking elsewhere.
As an aside, if you want to add extra currencies - e.g. bitcoin, other cryptocurrencies, labour hours, cowrie shells etc, then this would also be possible.
