Hi @ebud,
Thank you for contacting us! I tested this on the latest copy of the free version of the plugin and I was able to reproduce this issue, so I have notified our development team so they can investigate and get this fixed. For the Load More button, you can go to WordPress Dashboard > Twitter Feed > All Feeds, click your feed’s name or pencil icon to edit the feed, go to Load More Button, change the text value, and Save your feed.
It is currently possible to change to X branding by going to WordPress Dashboard > Twitter Feed > Settings > Advanced, enabling Change Twitter to X, and clicking Save Changes.
Sorry for the inconvenience. We are working on getting this issue with the translations corrected.
Best regards,
Louis
