Bug when used in combination with Pods

Hi, great plugin.
There’s just one issue stopping us from using it:
Whenever a page has custom fields added with the Pods plugin (https://www.ads-software.com/plugins/pods/), PixGridder gets messed up when saving the page.

Before saving, there is one row with two columns, both with text in it. After saving the page (that also has custom fields added to it), things get messed up:
There are now two rows;
The first row has two columns;
In the first column there somehow is a new row with also two columns. These two columns have the original contents.
The second column in the first row is empty.
The second row has two columns.
The first column is OK.
The second column is empty.
