Does have anything to do with the first screenshot?
Also is there a way to get to these setting yourself? Because I can't find it anywhere
Yes, both are related, one causes the other.
I haven't been able to find the enhanced features on this phones, I remember those messages and options from when I had the AT&T Galaxy S6 Active working on T-Mobile, it never registered because of the Non-AT&T sim card and it was annoying as hell.
As far as I can remember, the enhanced features were present on the Message App (SMS/MMS) and one of the features allowed you to send MMS with full resolution images because it saved the media on Samsung Servers and basically what you send was a link so the recipient could download and see the picture in full resolution, trying to make things similar to iMessage.
I can't find the settings or features at all on this phones but I think that it's because since T-Mobile added their enhanced messaging features the settings and options changed, maybe for other variants like AT&T or any other carrier or variant that doesn't include a carrier proprietary Message app, it's possible that it's still appears under Message or Contacts apps settings.
So I think that if you are not even interested in something like this or if it's failing for you, just get Package Disabler and disable it.
