### Agreement

- [X] I agree that my issue may be closed without action if it doesn't meet all the requirements.

Use the attached compressed package and screen recording to reproduce the invalid posts theme setting after importing the theme. Start with the Elementor theme/package import flow and compare the imported posts setting with the expected configuration; done means the imported site no longer reports the setting as invalid and the stated reproduction steps work.
