Error when removing an Element class URI

[beepsoft]

I am editing an Element and added two class URI-s to the Element.

When I try to remove one of them and save the element and error happens

screencast-cedar.metadatacenter.org-2023.06.07-09_50_52.webm

Here's the specific error I received:

{
    "errorKey": "invalidData",
    "objects": {

Thanks for this report. We are making some updates to the Medata Editor in the next few weeks and will try to tackle this.
