@Micjwoods Thank you very much for the reply,
@kirk74 Please do a testing for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it's fixed, you'll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
If that did not work, please create a new thread and provide us your site URL and login credentials in a secure note so we can take a closer look, you might have a different culprit of the issue on your end.
