Is it normal for the pronunciation of 'bakwul yeok' to sound unnatural when pronouncing Hanja?

Hello! It's been about a year since I came to Korea. I've been learning Chinese characters lately, and I'm studying the character '易' which means 'change'. However, when I pronounce '바꿀' and '역' together, I keep saying '바꿀 력' instead of '바꿀 역', and it's bothering me. I'm not sure if it's just me or if it's supposed to be like that. Has anyone had a similar experience? I've tried going to a Chinese character academy in Gangnam and asked my Korean friends, but I keep struggling with the pronunciation. I'm practicing my Korean pronunciation, but I don't know how to correct these pronunciation mistakes. If anyone has tips or can recommend an academy that can help with pronunciation correction, I would really appreciate it! Please give me some good advice~
