UTM + ACF issue

I just found a weird thing on the plugin while using ACF. I have a custom field named “URL” within a repeater and I made it a page link type. If I am going to activate the UTM plugin, the value of the custom field named “URL” will be changed into page ids rather than the permalink.

It goes something like https://mywebsite.com/services/123 instead of https://mywebsite.com/services/seo

What’s your thoughts on this? Thanks
