Problem:

I select three columns for the views, but it shows only 1 in the front end.

Solution:

It is a conflict with Flying Press optimization plugin.

- IMPORTANT STEP! Create a backup of your website.
- Go to "WordPress Dashboard > Plugins" and deactivate all plugins except Toolset and its add-ons.
- Check if you can still recreate the issue.
- If not, re-activate your plugins one by one and check the issue each time to find out the plugin that causes the problem.
