changing the color of the guide changes the weight of the guide

hi, okay so the issue is that when i change the color of the ruler guides, the different colors show different guide appearances. for example if i choose cyan color guide, then the vertical guide becomes thicker on the artboard. like idk why but the weight of the guide changes and the unusual part is that only the vertical guide changes and that too only the part that is on the artboard. please help fix the issue.
