Extra "r" Characters in Contact Notes - with Google contacts

I started to see extra "r" characters appear at the end of many lines in my Contact Notes on my iPhone and iPad. I sync my contacts on those two devices with Gmail Contacts. On my iPad and iPhone, the extra "r" characters appear at the end of the line where I have hit the return (enter) key. I don't see the extra "r" characters in my browser when I look at my Google Contact notes. I also have 3rd party software that syncs (Sync2) Google Contacts with Microsoft Outlook Contacts and the extra "r" characters are also not present in Microsoft Outlook Contact Notes. I only see the extra "r" characters when looking at my Contact Notes on my iPhone 12 Max Pro and iPad Pro. I started seeing the issue a couple of weeks ago when the iPhone and iPad were both running IOS14. Since that time, I have upgraded to IOS15 and the problem persists on both my iPhone and iPad. Any ideas why the Apple devices are inserting this extra "r" at the end of the line where I have hit the enter key. It is problematic. If I have put a period at the end of the line....the "r" will follow the period and it is easy to discern it is an added character. In other instances....I may have listed an account number or model number in my notes that is made up of numbers and letters without a period at the end....an added "r" makes it hard to discern if the "r" is part of the account number or model number or something that has been added in. Any ideas what is causing this issue and how I might resolve it?

Help!
