Strange unknown label appearing on 3D online
On the last applet I have uploaded to geogebra (https://www.geogebra.org/m/pyyfqm2c), there is a strange label appearing on the 3D view, which is definitely not on the .ggb file.
The label does not belong to the construction (nothing inside has that name) and it is also not shown nor using my installed geogebra nor while uploading the applet.
Why can it be?
(*) I am using windows 10, and the problem appears on all three browsers I have checked: chrome, firefox and edge.
