If I want to place an icon next to the text in “Hosting pricing table”, the text disappears. If I remove the icon, there is text but in responsive mode it says TEST in the place of the icon.
For your 2nd issue, Please provide your wp-admin (URL, Username & Password) access using our Envato Market (themeforest) profile contact formhttps://themeforest.net/user/themelooks#contact (screenshot as reference https://prnt.sc/10o0iwt ) including this support topic link as a reference to review the issue to fix.
We have reviewed your website and we have seen that you have used this pricing table https://prnt.sc/10t4aeh where has a Feature Level system/option that you didn’t set properly and only set a level called “test” https://prnt.sc/10t4dh0 that’s why “test” shows in the mobile as a Feature Level.
We are sorry to say that there is no way to get 4 columns instead of 3. As it’s a slider if you add more than 3 pricing tables then it will automatically be a slider.
