Blog option disappeared with Grav v1.7.0-rc.17 - Admin v1.10.0-rc.17?

Hi again everybody…
I’ve a little incident since I update (accidentaly) to GV1.7 rc 17.
Page option template “blog” disappeared (cf. image). I have to go to command line and move the to manually.
It’s a little bit annoying when I make some test and forget to convert.
How can I restore this option ?
(and it’s the same for “item”, not present, so no item for blog…)
thanks in advance :slight_smile:
