Subscribers list table not showing all columns

This happens if there were problems importing/updating the views.view.simplenews_subscribers.yml configuration.
A simple solution is to re-import the views.view.simplenews_subscribers.yml configuration.

Can you describe in more detail what caused the problem?

Thanks a lot. Reimporting views.view.simplenews_subscribers.yml indeed resolved the issue.
What caused the problem is a mystery to me though, all I did was:

composer require 'drupal/simplenews:^4.0'
drush en simplenews 

Installed versions:

drupal/simplenews                             4.0.0 
drupal/core                                   9.5.9  

Okay awesome. Reimporting that config fixed it for me.

The the problem was immediate upon a fresh install of 4.0.0. I'm on core 10.2. Don't have any other info beyond that. 10.2 was not a fresh install though, so maybe its conflicting with another module?

Wondering if this issue should be closed or remain open to further explore the underlying cause?
