2 øre 1917 - split into 2 lines [solved]

In Norwegian coin books, the 2 øre 1917 is divided into 2 lines; "Dobbelstrek" (Elaborated triskellion) and “Enkelstrek” (Simple triskellion)
Why are these varieties not on their own lines?

The prices and rarity are very different between the two.

Earliest book I can find in my storage that has 1917 mentioned with two different looks is 2006.

Probably because minting errors are NOT entered in the numista catalog.

In SCWC (KM) the double strikes are not mentioned

In UCoin, I saw your coin, I think, and nothing was mentioned about a double strike. 

Here is an example of a double stroken Chinese coin (1 den 1961, KM1, N#1005 , which is not and will not be included in the numista catalog:

In the case for the 2 øre though, the “elaborated triskellion” is the most common type of the year, so in my opinion it is more similar to the 1 krone 1908 mintmarks N#14690 or the 50 øre 2011 errors N#1442 or the TS over G for Swedish coins 1945 N#2787 and should therefore be considered to be on its own line.
I really am trying to understand how this is different enough not to be added.

@Sjoelund  Ole, you already made documentation on the coin page about this difference 😉

I think it's a design difference, if so a variant deserving it's own line …

I'm not sure they are the same.  Google translate for “dobbelt strek i trikvetra-symbollene” is “double line in the triquetra symbols.” There are no double lines in the symbol of Ole's graphic. Unfortunately, the picture of it in the catalog is too blurry to see it.  

But I do agree it is a variety and not a mint error.  Dobbelt strek does not mean doubled die or machine doubling which Ole was assuming it was (I think).

My documentation is not about a double strike, but a new designed triquetra symbol. 

It would be nice to have a hi-res image of the mentioned coin. Until then, I do not believe in it.

I think it's not a double strike (as in error with winting), but just a confusing wording in Norwegian and we are all talking about the same difference in design of the triskellion

Im not talking about a double strike eighter. What I am reffering to is two different designs.

So is it the same design as mine?

If it is, then you can argue for a new line, since all three marks are of the first design.
