oceanwp theme not working with elementor

I am using the Oceanwp theme, with elementor to build pages.
But there are layout problems when uploading images and texts(showing blank),
all other plugins deactivated, only activating elementor and elementor pro:

Using another theme(Business), worked properly, however
even when other plugins are activated. Screenshot as following:

PS. Ocean extra installed and activated.
