Actor Gary Sinese name just changed to Sinise

I was looking up information on this actor and after going back a few pages, everything just changed and updated to Sinise almost before my eyes. I have never had this happen and I believe it is in transition. I was looking at his IMDB page and when I went back, all the information just disappeared and has been replaced under Sinise. The page for Sinese still exists but is now blank.
