Germany 3 Mark 1913 - Defeat of Napoleon: Edge inscriptions

Hi,
I've recently got one coin like this one:
https://fr.numista.com/catalogue/pieces4713.html

I already have that coin in my collection, but after checking the 2 coins, there is a difference in the inscription on the edge.

One coin has the writing "GOTT MIT UNS" in "A" position,
and the second one is in"B" position.

Are these differences common ?
Do I have to ask a modification in the database (adding a new row for the edge position) ?
