All new posts are “Flamingo contact” post type

Hi,

I have this issue with a new customer : each time I try to add/edit a post, WordPress is trying to create a “flamingo_contact” post type. It happens with every post type : articles, pages, cpt…

And, instead of the title I get my account email, and into the text editor I have my email again, and my username.

When I deactivate Flamingo it stops. Everything is up to date, latest version of WP, template (OceanWP) and plugins.

Any idea ?
