Bug with Currency and Denomination drop-down menu [solved]

At first, I saw that the correct currency is not available in the drop-down of the editing page of Zutphen, City of • 6 Stuivers "Rijderschelling".

The screenshot below - taken from the editing page of another 6-stuiver piece - is what the correct information should be:

However, the editing page only allowed for these options:

When I checked the catalogue pages of other coins from the City of Zutphen, the Currency and Denomination menus were filled out correctly. 

However, when I opened the editing pages, the information in the fields and the dropdown menus would flash, then changed to either ‘Unknown’ or something else upon the editing page loading.

This ‘bug’ appears to happen for every coin from City of Zutphen, but I don't know if this is a broader issue for other (Dutch) currencies. While the other 6-stuiver piece mentioned early also flashed and changed, it stayed on the correct currency and denomination.

I think the problem is that we have the later Zutphen coins (during the period of the Dutch Republic) in Dutch States.  

And we do not have a Zutphen section in Dutch Republic.

I will do some work on this so that it works correctly on these kinds of changes.

Cheers!

And sorry to keep bothering youse 😅

The issuer Dutch Republic > Zutphen, CIty of has now been created so that the Zutphen coins after 1591 are collected under Dutch Republic (only a few earlier ones are still under Dutch States).  https://en.numista.com/catalogue/zutphen-1.html

So the currency problem should be corrected.

I've also added a few of the missing types.
