itunes only shows titles, no other columns

In iTunes, I could always see various columns (title, artist, album, date added, etc.)

I don't know what happened, but since yesterday it's only been showing the title.

I've never seen itunes like this before, and it's not good; I need my other columns too.

I've tried everything to get it back to normal, but

View Options looks like it used to do; Column Browser looks the same but I never use that.

Can anyone help,

thanks in advance
