Hi John,
I highly doubt that’s an issue with us or with any of the three plugins that you mentioned for that matter.
We suspect your WP install is corrupted.
I would try using the reinstall button, on the updates page after doing a backup of the site.

If the WP install is corrupted, then wouldn’t this update problem happen on all plugins and even WP updates?
Hi John,
That sounds logical. However, our lead developer who’s a contributor to WP Core recommends the above solution. You can do a backup of the site and then reinstall WP through FTP if preferred, being careful to not overwrite /wp-content/.
If that doesn’t fix the issue I’d contact your hosting company and look through the error logs with them and see if they can provide any insight.
