What would cause multiple error lines to appear using validator logic

Question

What would cause multiple errors to appear for a single line as shown below. I coded Regular Expression Validator with a specific matching pattern and all the patterns work fine. When I key in an invalid pattern on a row I get the following errors dislayed. Why am I getting multiple error lines instead of one. Also when the data in the field is in error the field gets cleared. How do I fix this problem?

Answer 1

Looks as though my RegEx script is not coded properly so it is causing the problem.
This is my regex script
8([0-9]{3})|8([0-9]{0,2}\%)
I changed the script above to the following to slowly build the script back to get rid of these multiple errors that are appearing. When I set my regex script to the following then I just get the one error line.
([0-9]{4})
I thought the regex script was working but when I key an invalid value I get 8 error lines as shown above. That should not be happening. This regex script
8([0-9]{3})|8([0-9]{0,2}\%)
is to perform the following logic:
The field I am editing is 4 characters long.
1) The first character must be an 8 and the next 3 charaters must be any character from 0-9
OR
2) The first character must be an 8, the next 0-2 characters must be any character from 0-9, the next non-blank character after any digits must be a wild card character of %
Examples: any number from 8000-8999, 8%, 8n%, 8nn% where n is any number from 0-9
