Responsive Carousel image too big

-- HikaShop version -- : 4.6.0
-- Joomla version -- : 3.10.0
-- PHP version -- : 8.0.19

Hello everybody!
I have a problem and i still don´t find a solution. I am going to use the carousel on my website. As you can see on the screenshots, the desktop version is looking very good and nice. But when i try to look at my homepage with my handy, what i get is the second screenshot..
What i want say, the carousel image of the product is really too big and doesn´t look nice..
Is it possible show the products of the responsive carousel on 2 rows or at least if on 1 row must be, a little smaller?
I tried already the advice i saw here on the forum in another discussion, to change the values of the responsive string in display- views-carousel, but it had no effect.
Thank you!

P.S I am using the template Protostar Plus.

Hi and thank you for your answer. Yes sorry, i was meaning columns not rows.
This solution you show me is exactly what i was meaning i tried and doesn´t work. It has absolutely no effect. even if i clean the cache.
Well, at this point is come me a doubt..Can it be maybe that this " Random products" module i activated from joomla and not hikashop, is not our hikashop carousel but something else?

Thank you! Finally i found the problem thank to your simple advice..i was going on and on to change the code line of Categories Carousel instead products Carousel..because of this it didn´t work. Now i finally got it on smartphone in 2 columns.
