Exception applying HTML template when condition applied

[NSBum]

An exception occurs when attempting to apply a condition on an HTML asset.

The condition is valid ["card", "=", "ru2en"] and for this note type, I have a card named "ru2en". If I remove the card condition, the exception goes away, but of course, the asset gets applied to every card, which is not desirable.

Asset Manager version 2.1
