Our embedded links stopped working properly after an attempted Joomla upgrade. Here is an example:

www.ruwacindustrialvacuums.com/products/portable-vacuums/portable-vacuums/the-red-line-series/ws-3420

You see that extra "portable-vacuums"? It was never there before, but has suddenly started populated across the board on all K2 categories. Why is this happening? If someone could please give us some direction, that would be much help!
