Can't delete campaign

For some reason, when I enter the name of the campaign in the modal, the delete button does not activate. Tried different browsers and different units.

It worked just fine deleting other campaigns.

I’ve tried delicious copy-pasta (of course) but that does not work. Nor typing the name in from keyboard. Or pasting it into notebook, seeing what font is…

I can’t get rid of the campaign!

I do NOT mind if you delete it for me. Please do if you have the option.
