1 column not 3 columns for gallery

When I upgraded to Catch Box 4.2.1 with WordPress 4.4.1 gallery went from 3 columns to 1 column. I cannot find CSS in Catch Box to fix this. There is a style gallery-columns-3 but I cannot see how WordPress and Catch Box theme interact to pass the data.column field to get right column layout (3 not 1). There is no Theme option to fix this. Earlier versions of Catch Box did not reduce columns from 3 to 1. 3 columns is set in gallery settings but Catch Box Theme is not displaying 3 columns. I use Gallery Carousel without Jetpack and I want 3 columns of images then when person clicks on one the carousel is opened. That works but 3 column layout does not since theme upgrade. This problem of 1 column not 3 columns does not occur with TwentySixteen theme only Catch Box 4.2.1 theme. Site: mepsa.org - click on gallery and any year - they are all 1 column now not 3 like before upgrade of theme.
