It took me half day for the system to kick in and not give me an error code, but now my flights are all with confirmed seats

I went to Finnair, deleted my ffn, logged out. Went back to Finnair and re-added it there. Logged out. Went to BA and the ffn is not there at all. Should I re-add on BA too?
