column issue on desktop

[caracas]

Sorry if I misunderstand something.

Bootone installed with joomgallery 3 + joomla 3.4.5
Bootone selected in layout configuration.
Menu link for gallery "view bootstrapped gallery" for both mobile menu and desktop menu.

• works fine and clean on mobile devices, shows one column for category/sub category/normal view

• possible issue: gallery shows only one column for sub categories, and detail views on desktop (4 columns for sub categories and categories in configuration manager).
  categories shows 4 column as espected.

If I use normal view (instead of botstrapped) in desktop menu, it is the same.
Joomgallery show only one column in sub categories and detail view.
setting is 4 column in configuration manager for sub gategories and categories
categories shows 4 column as espected.

OK ... may be I missed something, or is this an issue ?
Thanks for help.
