[v.2.3.3] Problem with graphic equalizer

Good morning
I carried out tests both on the computer that I normally use and on a clean virtual machine, with Windows 10 1909 operating system (build 19363.657)
In the section Effects>Graphic EQ … the message appears
“The requested curve was not found, it will be used ‘without name’”

When I press “OK”, the graphic equalizer appears without writing.

How can I solve it?
Thank you

The old Equalization effect was retired (discontinued) because over the years it had become buggy and it’s code unmaintainable.

Audacity 2.3.3 has the first version of two new effects to replace it:
Graphic Eq https://manual.audacityteam.org/man/graphic_eq.html
Filter Curve https://manual.audacityteam.org/man/filter_curve.html

The next release of Audacity (2.4.0, due for release quite soon) will have updated versions of the new effects. The main differences in these effects in 2.4.0 are:

  1. Graphic Eq gets frequency labels for each slider.
  2. Filter Curve has a name change to “Filter Curve Eq”
  3. Both get the ability to export / import curve settings.
