Metaobjects Validation Issue

[bkbkbk]

I'm trying to create a metaobject to link it with a button in order to make it a call button (i.e. "#tel:1234") 

When I'm trying to add the meta object I'm running into "Validations must be a valid domain." error. However, it explicitly says that "Values must be prefixed with: “HTTPS”, “HTTP”, “mailto:”, “sms:”, or “tel:”. I'm prefixing the value with "tel:" but still getting the error. Attached is the screenshot of the problem. I've tried different variations with quotation marks, without quotation marks, with # and without #. Any help would be appreciated. Thank you

Hi @bkbkbk , can you check if there are any blank spaces?
