Filter and ads looking weird

Hey,

I’ve changed the default slug (via php), added some css edits to the front end, added a new currency and all was good but somehow my adverts page went berserk with styling (too much padding and margins added, but they’re not in the code actually) and can’t seem to find the code to make it back to normal. I’ve reinstalled the plugin, changed to default theme, no luck.
