EasyBlog - Image Wall Module 5.1.5 broke with current Module Class Suffix

I have an EasyBlog - Image Wall Module on the home page in the grid13 position name Most Popular that just broke when I upgraded to EasyBlog 5.1.5.

However, I am not sure if this problem is with the module or with the template classes.

I have found that it is related to the module classes from my JoomlaBamboo template.

In the Advanced Module Class Suffix I have the following entered

zen-bg zen-tertiary1 zen-rounded

Those class suffixes are compressing the rows of this module together. If I remove them then the module displays in two rows that are not compressed. But, then I do lose the benefits from the Module Class Suffix which I am also using for the two EasyBlog - Showcase Module on the same page called "Articles & Blogs" and "Resources & Results" (in the grid7 and grid8 positions)

I would like to keep the module class suffix but if I have to I can remove it. I left it there broken now so that you could see it.
