Missing Emails and Errors on Email Addresses when replying with Mail.

I am experiencing two issues with Mail. I am on Sequoia, and the email account is a proprietary domain on Google through Cloudflare DNS. The account is connected through IMAP.

1. The first issue is that sometimes the most recent emails are lost of the inbox for a while and then after a maybe 10 minutes they appear again on the inbox. This only happens to emails of the last couple days, say 2-3 days and for some briefs moments (about 10-15 minutes) its not a connection to the server error because the emails are downloaded initially is that when I try to go back and check a previous email they are gone until they appear back.
2. The other issue is that some emails I am receiving, if I check them in Mail the senders and CC's email addresses are all mess up (see image).

They seam to lost format and so I cant reply back to from Mail. This is happening mostly with the same senders, but I have encountered the problem with senders from at least 2 different unrelated domains. The issue is also happening on Mail on iPhone, which leads me to believe it's a Mail issue.

If I go to Gmail and see the email there, everything is fine and I can reply back with no issues.

Any idea of what might be going on would be appreciated.

Thanks,

T.
