Branding domain being stripped in outlook when using VML code in the template

After a rebrand this winter, we noticed our CTAs were being stripped of their formatting in outlook clients. So we added the VML coding to the template and recently we started seeing the branding domain was not working on these CTAs, in outlook only, it will show the full url when you hover over the CTA. Does anyone have any ideas on how to rectify this. This is the VML code around the CTAs.
