well, now it is looking quite crashy:
Deleted old plugin, installed new one. It is showing version 1.0.1 now.
The idea is to show only 1st field as a preview. Not all of them. But anyhow it is now not working correctly. (There are russian symbols in table fields).
On frontend it is working good, as before.
sys: WordPress latest, Google Chrome, OS X Sierra, Page Builder 5.4.5
