Hello,
That's not really so simple, you can understand that in order to help you we have often to perform some tests to understand situation and so, better help you.
And with time we have a lot of different version of HikaShop and some times option can be re-organized in order to be more logical (and move from a configuration part to another), or in other case some options may had been removed.
In your specific case, and thanks to your last elements we can now understand from which back-end configuration page we talk.
Now for the front-end context, where do you have 3 columns instead of 2 ? On a module ? on a listing (via item menu) ?
Without these details, it's impossible to help you.
Remember more you help us, better we will be able to answer you.
With this same idea, provide screenshot from back-end is possible if you log in English just for perform the screenshot.
Awaiting news from you.
Regards
