Custom Tokens in views with ?=x arguments gets repeated if used to Rewrite output as a link

When ever field in a view is a 'custom tokens' field and the 'link path' uses a 'replacement pattern' that is also a 'custom token' field with ?xxx= anything in it gets repeated twice in the output.

For instance if a 'custom field' is example.com/t.php?id=10&?ref=20, and views Output this field as a link the output will be example.com/t.php?id=10&?ref=20&id=10&?ref=20_

The anderscore also apears every time at the end.

I have tried all the switches but no avail.

Only way I could go around this is by using a custom formatter with it that would do what I needed.

Help would be apreciated
