Thank you for waiting. I have checked your questions again.
For textblock element issue, this is bug of Visual Composer plugin and i have fixed it for you. Maybe it will be fixed in the next version of Visual Composer plugin.
For contact form issue, to display contact form, you need to use ‘Location content’ tab to build content for location. I have built sample tab for contact form. Please check it again. You can refer my attachment or our document to more details.
I think visual composer will fix frontend editor bug on the next version.
For the words alignment issue, I can find your custom code css in Theme options. I have removed it and it’s working correct.
