Recovered "Recently Deleted" messages are getting deleted again

Hi,

I had a thread that I mistakenly deleted in imessage and was able to recover it. I went to "Recently Deleted" and hit "Recover". This worked great and I was very happy to know that this feature existed for these types of mistakes. However, every day I check the thread and see that random messages in the thread have been deleted. At first when I noticed this, I figured it was a small one-time glitch and checked the "Recently Deleted" again and, low and behold, there were the random deleted messages. I recovered them again and all was well. The issue is, this is an every day occurrence now. Every day, when I wake up and check the thread, there are random messages deleted from it, and I start the recovery process over again. The reason I am concerned is that the countdown is the original countdown from when I accidentally deleted the thread to begin with. I am worried that if these random messages (well over 100 messages, including pictures) keep getting deleted from the thread and the countdown is still active, after the 30 days are up, they will be permanently deleted. Is this something anyone has come across before and been able to solve?

Thank you!
