I have also noticed that the results of the filters vary depending on whether in the mega menu I click on one subcategory or another.
You can do the test by going to the mega menu and clicking on “Aceites, especias y salsas”, and once the web is loaded, filter with the radio buttons.
And then do the same but clicking on “Legumbres, Pasta y semillas”, and filter with radio buttons. You will see that the result of the filters is different.
