Website jumplink issues with email buttons

Hi everyone,

When we insert a link with an internal jumplink (i.e., www.example.com#form-- note: just an example, not a real URL) into the URL on an email module including a CTA button, it does not work. Instead, the jumplink portion seems to be erased, so it just goes to, hypothetically, www.example.com.

When I click on the button in a sample email or in the preview, it renders as www.example.com + a bunch of Marketo munchkin code and ends with #form? 

I am not sure why the question mark is being added. I've double-checked that in the URL field in the email module, there isn't an extra space at the end of the URL.

However, the jumplink hyperlink works correctly when I insert hyperlinks directly into the text box. It only seems to be an issue with buttons.

Any insights into why this is happening? The only way I can think around this just clicking on the button in the text field and manually inserting the URL there as opposed to in the module section in the email design.
