WPBakery Page Builder Short Code not replaced on frontend


I have installed WPBakery Page builder plugin and i’m running wordpress multisite. From admin i have created a page using WPBakery page builder.

If i open the frontend page it’s showing with short code like below.

[vc_row][vc_column][vc_column_text]I am text block. Click edit button to change this text. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.[/vc_column_text][/vc_column][/vc_row]

Actually the short was not replaced here. Please help me how to fix this issue.
