redoing the upgrade resolved this

Hi @will.graham and thanks for confirming that you’ve solved the issue.

I’ve seen that a few times already and this is usually happening when the javascript files are not being updated properly, so when there’s an issue with the upgrade commands run and some files in the web directory are still from the old version.
Rerunning the upgrade must have fixed that for you gladfully.
I’m marking this as resolved now.
