Thank you for the support question. I’m so sorry for the inconvenience you are experiencing. We do know about this issue, which has occurred since the introduction of WordPress version 3.9. We are currently working on this fix plus a number of other conflict resolutions and improvements. We will push this update out as soon as we can.
In the meantime, you can use the Information icon in the code block toolbar to obtain the shortcode ID.
Hope this helps.
