Shortcut alphabet moves the 'W' letter after J

Is this is a metadata problem or a French quirk, here the W listings are after the letter J, not as expected after the V.
If the W is clicked, the listings start at J artists like Joe Jackson. If the regular J is clicked, the first J like Jackie DeShannon is shown.

Here’s what the listing looks like.

Hi @One-and-a-Half,

If you have the W in the middle of the listing, then we need to check your sorting & the metadata of the tracks you have. Can you please send a screenshot of your whole interface so we can see your sorting and the albums you see when you click on W?
