Charts not saving with favorites

Hi there,

When I create a chart via the Event Report or Event visualizer and then try
to save
the chart (favorite --> create, enter a name and click create) nothing
happened,
it's not saving. Therefore, I can't import these charts to my dashboard.

It was working before, I have previous charts I saved before.

Does anyone encounter this kind of issue before?

Thanks
