So when i create or edit my WhatsApp templates trough meta web portal, it seems that there is kind a problem with call to action buttons and dynamic URL.

My dynamic URL looks like:

https://www.my-website.com.co/payment?reference={{1}}

Where {{1}} is a alphanumeric value, for example:

https://www.my-website.com.co/payment?reference=12345678

But for some reason, when i submit the template, a slash is added between my URL and the dynamic value, so after the revision is confirmed, if go back and edit again the tempate, the slash is added:

https://www.my-website.com.co/payment?reference=/{{1}}

When I use the template to send an message, obviously the button is not working because URL is not well formed:

https://www.my-website.com.co/payment?reference=/12345678

Thing is that this was working fine some weeks ago as I was able to create templates with no slash automatically added, but now is completely broken, there is no way to change it.

I am going to try editing it trough API call, but do not thinks it going to help me.

Attached to this ticket you can find a screenshot for better understanding.

Will appreciate any help in case I am doing something wrong.
