One issue I noticed was that if you turn off the picture description it still says Description:. I fixed this by editing the adv_portal_album_pictures_bit template.
Find
Code:
<br /> <strong>$vbphrase[description]</strong>: $picture[caption]
Replace
Code:
<if condition="$mod_options['album_picture_description']">
<br /> <strong>$vbphrase[description]</strong>: $picture[caption]
</if>
