Problem with visualization of collection

[Peachy]

I don't know if it's the good section to post but since this morning I've some troubles with the visualization of collections.

When I choose between the three types (just the front cover, little front cover and text and only text), no matter what I choose, it only remains on the type "little front cover and text".

And it does not happen only for my collection , but for all the collections that I look.

So I wanted to know if it was some kind of bug and what to do to remedy it.

Thanks
