News view thumbnail image size is too big

The current thumbnail image in the News view on the front page is too big. 

I did the following:

1) In Edit View window of News block, opened FIELDS > Content: Image

2) In Configure field: Content: Image window:  Image style:  trying to find “Landscape thumbnail old” but couldn’t find.

The “Landscape thumbnail” which is the current setting is too big. How to get ”Landscape thumbnail old” back?

Thanks,
