Same issue! This is a really basic error and shouldn’t take too long to fix. But I won’t go about telling you how, because I’m not sure of all the inticate plugin details.
But what I did end up doing was changing wthf_types update_option line. I started out by just always updaiting to empty array. That did uncheck both option on options page, but also it started to show helpful block on all pages and posts. Bad design!
Then I changed option updatu to array with single string ‘no-type’ and that seems to be working e.g. not showing any helpful blocks by default on any post or page.
Now I can go about and use the shorcode you have created, but am not sure why there is one if you can’t even turn off default outputs to contents.
