Visual Composer code showing on pages

Hi,
I’m working on an inherited site. Originally the site was created in WP Bakery, I have switched to Enfold and I am cleaning up the content on a development site.
The posts have come across fine but pages are displaying code where each original section began eg :

[vc_row full_width=”stretch_row” css=”.vc_custom_1510844578665{background-color: #000000 !important;}”][vc_column][vc_column_text]

I can delete the code without losing any material but there are hundreds of pages. I am looking for a way to remove these globally and I’d be grateful for any suggestions.

I have tried deactivating all plugins.
