I’ve reported some time ago in Github a problem when, inside a cloze text, there was a Rem Reference.
The problem was solved, but now I observed that, although the card generation and queue are not having problems (as they were when I first reported that issue), the Rem meta data is not being show, and an error occurs when the command /data is used:
This error is not restricted to Beta server (Version 1.3.7). The stable version 1.3.6 also has this issue.
