Whirlpool Refrigerator Cooling Problems

Hello everyone, I'm Umut, and I own a Whirlpool refrigerator that has been a mixed bag of satisfaction and disappointment. While the freezer compartment works like a charm, maintaining the temperature and freezing everything properly, the regular refrigerator section falls short on keeping things as cool as it should.

I've tinkered with various settings in an attempt to remedy the issue, but alas, no success. It's becoming a bit of a headache as my food isn't staying adequately chilled, leading to some real inconveniences.
