Extra tabs on products

I imported my products, and now they have tabs for features and tags that show up on the product page. Is there a way to remove these two tabs?

Also, for some reason the release date for my products is set for 1969. I thought that deleting the date would fix it but it just keeps going back to that date if I leave it blank.

I have almost 1000 products so removing the tabs individually can take some time, is there a way to remove all the tabs I don't want at once?

nevermind, got it
