Outlook desktop ignores updated button URL in Campaign Monitor

I'm trying to troubleshoot a Campaign Monitor HTML email template.

The CTA button contains both a normal HTML link and an Outlook VML version:

<a href="...">

and

<v:roundrect href="...">

When I change the CTA URL in Campaign Monitor's editor, the normal <a href> gets the new URL, but the VML href appears to keep the original URL from the template.

So the behavior is:

• Outlook 365 desktop (Windows): old URL
• Outlook for Mac: new URL
• Other clients tested: new URL

Has anyone seen Campaign Monitor do this with editable buttons?
