I'm creating a post type by inserting all the data, but when I click on support and uncheck the thumbnail option, the post loses the name entered and whenever I write the name again it always leaves the field clear, I believe it's a bug in the tool .
This error occurs whenever I uncheck the thumbnail option in the support tab, that is, the tool requires my post to have a thumbnail image.
The development team is aware of the issue with Plural and Singular names of the CPT and working on it. It will be included in the next update of our plugins.
