Out of alphabetical order. In these prints you can see the letter V before the E for example in both scrolling options.
You can notice also that in both prints when the letter is selected in the alphabetic bar it doesn't go to the first game of that letter.
Ok, this is very strange

I have some questions if you don't mind to take some time to help me debug this:
- I see in the second pic a ' label, can you go to that label and tell me some game names for that label? I could incorporate that in the "#" label but this is a minor issue...
- Is your current filter sorted in some special way? Or is it just sorted by name?
- It's very strange not only that V is before E, but also that M is present twice in the list, gonna check the case of this letters. Also, what are the games in the "V" label? Any strangeness in their names?
I didn't have these issues on my test machine, but I got some issue on another machine with way more ROMs, so now I'm syncing my machines and already found and squashed some bugs, if you can help me wth this it will be greatly appreciated. I think the issue is in the way my theme generate the sort order, for some reason my routine places a "V" before an "E", but it didn't happen in my tests...
