Date Off Flan - Dateless - Undetermined [Risolto]

Many medieval to renaissance period denars, deniers, solidii, etc. were minted very poorly and centering wasn't the minter's concern.
So for those of us wishing to catalog our collections, we need a category for these undetermined coins.

Recently I submitted an entry correction for this coin:
https://en.numista.com/catalogue/pieces84607.html

it was quickly rejected by geralttt saying why don't i just use the Undetermined category?
CAN ANYONE SHOW ME THE UNDETERMINED CATEGORY IN THIS LISTING?

here is what i see in the English page version of this coin, each have dates:

Just below "Manage my collection", click the arrow icon by "Add to my collection" to bring up the add coin page. Choose the date in a drop down at the top; in this case, select Undetermined.

The Undetermined date is hidden by default so you don't have to see it if you're not using it.

Cita: "Outsider"​Just below "Manage my collection", click the arrow icon by "Add to my collection" to bring up the add coin page. Choose the date in a drop down at the top; in this case, select Undetermined.
