The newly created custom post type name is not showing up in the WordPress dashboard - left sidebar. I have deactivated all plugins (except metabox and metabox AIO). still no luck. I am attaching a screenshot for reference.
I have assigned the menu position after "fluorescent proteins". Fluorescent proteins is another CPT created a couple of years ago.
one possible reason is I might have created CPT with this name years ago. Other than that I can not figure out what went wrong.
