Information files and Comment tags

[timster]

I have a few pdfs for some albums, so thought I'd try the information files feature. From the manual, it says you need to add the Comment tag to itemTags, and set its displayFormat to the URI string. Is this the only way?

Because, after a bit of detective work for what I thought was another problem (see below*) it seems that albums that already have a Comment tag value are clashing with this function.

*some my albums started showing as unavailable on the control point (strike through note in Kazoo), and the only common denominator I can find is that they have the Comment tag already set (usually a vendor ID by the looks of it).
