New Name for Global Content Block not appearing in button dropdown

When I use the text editor button first time to insert global content blocks, it works. But if I then go and create a new global content block and come back to the same page, the name for the new global content block doesn’t appear in the button’s dropdown. If I exit the page and the come back, or if I Ctrl-F5, I still can’t see the new content block name. This is an issue for me and my client because obviously you want to use it straight away without using the shortcode. Can you replicate this at your end?
