CMS Sort Filter is case-sensitive

Hi there,

I just realized that the CMS dynamic list sorting filter is case sensitive, meaning that when I do have a shop list with names like “Amazon” “Bol.de” “Viking” and “titus” - titus will not be in its place between B and V but is sorted at the end of the list.

Correct:
Amazon
Bol.de
titus
Viking

Incorrect (displayed within my site)
Amazon
Bol.de
Viking
titus

Is this a bug?

You can see it live here on this screenshot. I changed “posterjack” to “Posterjack” and its sorted in a correct way.

Before:


After:
