Hello Michael

Thank you for your interest in our plugin.

If you use the responsiveness feature in a table, you can choose which columns will collapse on mobiles and/or tablets, so if you have a table with 10 column, you can have 4 columns visible at all times, and the other 6 columns would collapse below the 1st column. They'd be displayed by clicking on the "+" symbol.

Please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

Hello again Michael.

This sounds like a conflict with some other plugin you have installed.
