JS-Error "fieldName not defined in message"

[nwm-dev]

Using gridelements v11.0.0, clicking on any page in the tree using the page module throws a JS error "fieldName not defined in message". This is reproducable in a fresh TYPO3 11 installation. I set up a fresh installation with ddev, added a page as siteroot, did `composer require gridelementsteam/gridelements:^11.0", did the necessary DB changes and finally clicked on my created root page.

Screenshot of the console error if it helps:

I don't know yet if this has any consequences.
