Hello,
Does your other sections are showing? If not, it may be due to not assigning a home page setting as a static page in the customizer. To do that, please go through Appearance > Customize > Homepage Settings and select a static page. Note, the selected page must be assigned as frontpage page template.
If it is about for only mentioned sections then, please make sure the client section is not disabled on the customizer section. To check, please go through Appearance > Customize > Front-page Options > Client. Same situation for the service sections. Regarding the pricing it may be cause of not coping and pates the short-code on the customizer.
Please have a look at the theme documentation for more detail. https://keonthemes.com/doc/business-gravity-pro
