I was struggling with this too after upgrading today. The list was empty for me too and no refresh would help.

I was able to get it working by doing the following.

System > Settings > Add-ons > Search

Once here, search for "subtitles".

All the subtitle add-ons popped up and then I enabled them.

Then I went back to the System > Settings > Video > Subtitles

And they were there.

Not a clean way but at least this got it working!

Always a few snags with most upgrades but XBMC is by far best media center so I will deal with the little issues.

Hope this works for you!!
