I have setup Magento 1.9.3 on my server and uploaded all products and categories from admin panel, but when i go to front-end category page and filter products by category/size/color.
But in the result the selected filter shows twice in layered navigation. I have checked layout xml and html but I didn't get why this is happening.
See the attached screenshot:
In my case layer_view
block was called twice insidecatalog_category_layered
block in catalog.xml layout. I removed one and problem had been resolved.
