Odd display of brackets on Card

[phspaelti]

I am using the following markup on my card:

<div class="phonetic">[{{Phonetic}}]</div>

This is the output that I get:

I’m pretty sure when I first made these cards, the phonetic form actually displayed between the brackets.
I distribute these cards to my students, so this way of displaying is very confusing.

I guess I can answer my own question. Apparently the entry was enclosed in <div> tags. I’m not sure where these came from. There is an HTML editor in the Browser which allows me to see this, and change it.
Unfortunately I’m not able to spend enough time in Anki to really become fluent with all the features.
