Evaluation Gauge

The Evaluation Gauge slider does not work. Whenever I open the settings and switch it off, then go back the evaluation, nothing changes. Upon returning to the settings, I see that it switched back on.

Apologies for the low gif quality, I don't know why it is like this.

It's the same bug for me.
