NO page in Page Builder (All Albums)

How can I set custom width for the page:

BOONEX_DOLPHIN/m/photos/albums/browse/all

I don't see this page in the Page Builder... May be via PhpMyAdmin? But where can we find this option? In which table?

Sorry for UP, but I need an answer for this question )))

And not only me in future ))) Thx in advance!!

Pages which aren't in page builder use the same default width, which can be changed using the slider in the bottom of pages builder (on any page) - Other Pages Width.
