Illustrator 2024 : Color not matching after changed

I have a problem with the color palette in illustrator, it's happening to me and my colleagues at work.

For example, at first I selected the color code F6F086 and clicked ok, but immediately after checking the color code again, the parameters were changed from C: 5% to 6% and Y: 60% to 59%.

 And there is another problem: when transferring files, the file will have a skewed artboard.

Please, someone assist or find a way to solve this problem.

Thank you everyone for reading my article.
