Waves plugin not displayed correctly...

Hello, I just bought Wavelab elements but I found (of course immediately AFTER I purchased it… :frowning: ) that the waves plugins are not displayed correctly:
when you open their GUI only the bottom thin slice of them is rendered, shifted at the top of the window. All the remaining window is black.
They are unusable.
Any suggestions?

Are you using both the latest WaveLab and Waves plugins?

Windows or Mac? Any certain plugin or all?

Using the latest version of Elements 9.5.15 and the latest version from Waves, I tested a few random plugins and they look OK here.

Picture attached.

Mac. Updated to the latest version and now it works correctly, thanks.
