The registration should be inheriting the registration setting from the DotNetNuke at the site level.  These are the "Site Settings".  Do you have a page set for where registration happens?  What happens when you click registration on the login area?

I just had someone check the code.  The register and login link are using standard DNN API and code conventions.  We are requesting the registration link from DNN.  All of our test sites seem to behaving correctly.  Is there any reason why your site is non-standard?

Do you have an external link that you can provide where this is happening?
