Adding Featured Image not operating properly

I am trying to help add a new team member to this site. They are using the plugin called DV Team Plugin. I have no issues in the past. Currently I can not add a featured image, which is required to post the new team member. The option for “Add Featured Image” is present, but when selected then Media Library screen is different than usual, and once an image is selected there is no way to return to the new member screen to publish.

Here is how the Featured Image appears: https://ibb.co/1s3nbvB

Here is how it should look, as it does with a new page: https://ibb.co/mzLf4fJ

Any help would be much appreciated.
