Do you run a nostr relay? If you don’t back up your profile on your own relay this happens sometimes. Kind of a trade off that you can not be censored, But running your own relay gives government officials a total record of your posts. Otherwise you can just take what you can get on public relays. 

 Thanks. I don’t run my own relay but might look into it 

 Also many relays helps. I have 35 I am connected to I think. Look on my profile and click on relays. There are a lot.
