Collections issue

[fvlaicu]

Description:

I am trying out the new develop version that has the code for collections committed in.
I am noticing that when browsing a library that has collections, the alphabetic sorting is off. I assume it's because of the collections.

i.e. Pressing the letter L would take me to movies starting with J.

Details:

• Add-on version: latest develop version
• Kodi version: 18.9
• OS Platform: Any
• Hardware: Any

Checklist

• I have included a link to a log (or at the very least a link to a forum post with a log) from a session that had the issue
• I have added appropriate GitHub labels
