"Double" modal appearing on Add action across all entity Add pages

Suddenly "out of nowhere" when I click on a Radzen-generated CRUD "Add" button to open a modal and create a new record, the modal is doubled as shown in the image with one over-laid the top of the other. Clicking Cancel dismisses the modal as expected. I've gone so far as a full reboot, opened it and ran in Visual Studio, all with the same result. I've also noticed that it doesn't matter which "Add" page I click on for different entities, the modals for those are doubled as well. Anyone seen this before?

I did figure it out... In MainLayout.razor, for some reason a element was added in automatically. Removing it resolved the issue and didn't affect anything else.
