Adding Columns Inside Columns

My client is using the Enfold theme and the Church demo. The pages are created using columns, 3/4 and 1/4. Inside that 3/4 column I would like to have 2 columns per Text Block. I tried using the following shortcodes:

[av_one_half first]
XXX
[/av_one_half]

[av_one_half]
XXX
[/av_one_half]

But doing this broke the forth column and the titles of the columns do not line up. I tried adding:

<div class="entry-content-wrapper clear fix"></div>

between the “halves” but that would line up the titles, but the 1/4 column was still broke. I am attaching screenshots so you can see what I mean. Maybe Kreisi would consider adding a function so you can add columns within columns using the Layout Builder.

Thanks in advance for the help,

Scott
