Help with settings of Widex Evoke 220

Hello. I’m from Bulgaria and sorry for my bad English but I need help. Recently I have new devices (widex evoke 220) and I have a small problem with them.I try to explain to my audiologist but they don’t understand me.They put the program from the old hearing aid into the new one, but I don’t like it. There is a constant background noise that I don’t know how to explain to isolate it.And it makes my hearing worse and I don’t understand human speech very well because it focuses on other noises. It sounds like a broken program on the TV. I clarify that when I do settings through the Evoke app it gets even worse and the noise gets louder and there is no focus on the human voice In a quiet environment you don’t feel this background noise, but in motion and outside it’s a lot and it drives me crazy. And when I talk to someone, my speech is not clear and it’s kind of muffled.I hope you understood me. I don’t have this problem with my old device and I can hear perfectly.
It’s important for me to communicate and right now I’m a little depressed about the fact that I can’t hear well and my work is getting worse.
Thank you for your opinions.
