LibreOffice does not seem to understand that characters V and W is regarded as the same character in the Swedish alphabet. For example the string ‘Wa’ is supposed to come before ‘Vo’ after sorting.
This sounds like an information but not like a question. Are you trying to report a bug? If yes - report here: https://bugs.documentfoundation.org/
However: Svenska alfabetet – Wikipedia tells:
W ansågs allmänt som en variant av V fram till 2006 då Svenska Akademien i den trettonde upplagan av Svenska Akademiens ordlista över svenska språket började sortera W som enskild bokstav.
“Svenska Akademiens ordlista över svenska språket”, which AFAIK is the authoritative reference for the Swedish language, separated V and W in the 2006 edition. I should think that this implies a new rule. V is before W, not equivalent.
To force the old sorting on a table, you can make a helper column where you replace every occurrence of W with V, and sort on that.
If the sort column is A, try =SUBSTITUTE(UPPER(A1);"W";"V") and copy down.
