This set gave me issues also. .

Personally, I found I had a bunch of copies of the same files in those folders.
Probably from installing multiple times.
So I deleted the RT folders for that set and re-installed.

The folder's content looked better then, but I still had a few RTs saying N/A in the RT picker.
Yet if I selected them, they worked .. just mentioning this, since the same set of RTs gave me weird issues.

I will preface this (after the fact) that I participated in Beta testing and may have had beta type files cached/installed, which could compound my specific issue.
But '236' did ring a bell.

I do not work here, but the benefits are still awesome
