Why other people can't see my Validation Rules in VBS?

Summary: I did create a validation rule but another person want to see it to modified it but is not able to see it.

Content (please ensure you mask any confidential information):

I can see one rule created by me but other people no, they see this in the same page.

Are the validation rules restrictive? If I create a rule, only I can see it—others can't see it. Or is there a missing role or privilege that would allow others to view them?
