Hello all!
After much testing and wringing of hands and gnashing of teeth, we have ourselves a bug!
It is going directly into the ExpressionEngine backlog for Real Quick Work™
In the meantime, there is a workaround. For the entry you want displayed, it needs to be assigned a category. Even if that category is in a completely different group, and not the same as the others on the category page, it will side step the bug.
So, primeinc,
If you assign your Store Info channel a category group, and then assign a category to your store-info entry, it will show up on your category pages. It’s wonky, but there is a bug in the SQL that is executed when category are triggered.
Let me know if you have any questions!
Cheers,
