I am facing something weird in one project that I don't know if is normal (I hadn't seen this behavior in another project). The customer reports to me that when you enter to Category first page, products and filters are displayed right. However, they detected that when to open the filters and see the options, this doesn't show all the desired. In the category are products with valid values in that filter, but that values are not displayed in the filter.
I know this could happen by cache or indexer. However, something weirder happened when I tried to change to another page, change the number of products by page, or change the product order. On each occasion, the filters options change.
For example, in Page 1 I see:
Filter 1 -Option 1 -Option 3 -Option 4 Filter 2 -Option 2 -Option 3 -Option 4
And when I change to Page 2, the options changes to:
Filter 1 -Option 2 -Option 4 -Option 5 Filter 2 -Option 1 -Option 4 -Option 5
It is like the filter show only the options corresponding to the products that are on the current page. But is it normal? I had never seen this before. I this configurable in some way?
Thank you for your help.
